cIAP Antibody

cIAP Antibody

Catalog# : 3325

Apoptosis, or programmed cell death, is related to many diseases, such as cancer. Apoptosis is triggered by a variety of stimuli including members in the TNF family and can be prevented by the inhibitor of apoptosis (IAP) proteins. IAP proteins form a conserved gene family that binds to and inhibits cell death proteases (1 for review). The two isoforms of c-IAP (c-IAP1 and c-IAP2) are structurally related to XIAP, containing 3 baculoviral IAP repeat (BIR) motifs that are essential and sufficient for the binding and inhibition of caspases–3, –7, (2,3). The c-IAPs can associate with the death receptor TNF-R2, and mediate the ubiquitinization of TRAF2 following the binding of TNF-alpha by its receptor (2,4). Omi, a negative regulator of c-IAP, inhibits its activity by catalytically cleaving c-IAP (5). Another negative regulator, Smac/DIABLO, acts by enhancing the auto-ubiquitization activity of c-IAP (6).

Chk2 Antibody

Catalog# : 2391

The p53 tumor-suppressor gene integrates numerous signals that control cell life and death. Several novel molecules involved in p53 signaling, including Chk2 , p53R2 (2), p53AIP1 (3), Noxa (4), PIDD (5), and PID/MTA2 (6), were recently discovered. The checkpoint kinase Chk2 is the mammalian homologue of yeast Cds1/Rad53. In response to DNA damage, the checkpoint kinase ATM phosphorylates and activates Chk2, which in turn directly phosphorylates and activates p53 (7,8). Chk2 serves as ATM downstream effector to mediate activation of p53. Chk2 also phosphorylates and activates BRCA1, the product of a tumor suppressor gene that is mutated in breast and ovarian cancer (9).

CDIP Antibody

CDIP Antibody

Catalog# : 5047

The p53 tumor-suppressor gene integrates numerous signals that control cell life and death; loss of its functions contributes to the development of most cancers. CDIP is a novel pro-apoptotic target gene whose inhibition abrogates p53-mediated apoptotic responses. Overexpression of CDIP induced apoptosis in transfected cells while siRNA suppression of caspase-8 mRNA blocked this CDIP-induced apoptosis, indicating that the CDIP-dependent apoptosis pathway proceeds through extrinsic cell death pathway. CDIP may thus represent a novel target for drug design to maximize p53 response and sensitize tumor cells to cancer therapy. Multiple isoforms of CDIP are known to exist.

Caspase-9 Antibody

Caspase-9 Antibody

Catalog# : 2073

Apoptosis is related to many diseases and induced by a family of cell death receptors and their ligands. Cell death signals are transduced by death domain containing adapter molecules and members of the caspase family of proteases. A novel member in the caspase family was recently identified and designated ICE-LAP6, Mch6, and Apaf-3 (1-3). Caspase-9 and Apaf-1 bind to each other, which leads to caspase-9 activation (3). Caspase-9 is also activated by granzyme B and CPP32 (1,2). Activated caspase-9 cleaves and activates caspase-3 that is one of the key proteases, being responsible for the proteolytic cleavage of many key proteins in apoptosis (3). Caspase-9 play a central role in cell death induced by a wide variety of apoptosis activators including TNFalpha, TRAIL, anti-CD-95, FADD, and TRADD (4). Caspase-9 is expressed in a variety of human tissues (1,2).

Caspase-8 Antibody

Caspase-8 Antibody

Catalog# : 3475

Caspases are a family of cysteine proteases that can be divided into the apoptotic and inflammatory caspase subfamilies. Unlike the apoptotic caspases, members of the inflammatory subfamily are generally not involved in cell death but are associated with the immune response to microbial pathogens (reviewed in 1 and 2). The apoptotic subfamily can be further divided into initiator caspases, which are activated in response to death signals, and executioner caspases, which are activated by the initiator caspases and are responsible for cleavage of cellular substrates that ultimately lead to cell death (reviewed in 3). Caspase-8 is an initiator caspase that was identified as a member of the Fas/APO-1 death-inducing signaling complex (4). The adaptor molecule FADD couples procaspase-8 to the Fas receptor death domain; subsequent oligomerization promotes procaspase-8 autoactivation (reviewed in 5). FLIP, a catalytically inactive caspase-8-like molecule inhibits these interactions and thus can inhibit apoptosis (6). This antibody will only detect isoform E of caspase-8.

Caspase-7 Antibody

Caspase-7 Antibody

Catalog# : 3465

Caspases are a family of cysteine proteases that can be divided into the apoptotic and inflammatory caspase subfamilies. Unlike the apoptotic caspases, members of the inflammatory subfamily are generally not involved in cell death but are associated with the immune response to microbial pathogens (reviewed in 1 and 2). The apoptotic subfamily can be further divided into initiator caspases, which are activated in response to death signals, and executioner caspases, which are activated by the initiator caspases and are responsible for cleavage of cellular substrates that ultimately lead to cell death (reviewed in 3). Caspase-7 is an executioner caspase that was identified based on its homology with caspases 1 and 3, as well as the C. elegans cell death protein CED-3 (4). Alternative splicing of Caspase-7 mRNA results in the production of 3 distinct isoforms (4). Caspase-7 activity can be directly inhibited by XIAP expression (5).

Peptide Arrays

Bio-Synthesis of large numbers of extremely affordable custom peptides has never been easier ...

Bio-Synthesis has developed high throughput custom peptide synthesis to meet the growing demands for synthetic peptides in the proteomics boom. We offer parallel synthesis of small quantities of peptide libraries with the fastest and most efficient high throughput, delivering 96 different peptides, unbound, in a 96-well format. Each plate is individually tested for accuracy and can be used for epitope mapping, libraries, protein characterization and much more. This technique provides researchers the ability to order large numbers of peptides at extremely affordable prices and delivered in a short time.

A major reason for the demand of high throughput peptide synthesis has been the realization that synthetic peptides have become invaluable tools in elucidating important contiguous epitopes that are essential for functional and structural domains in proteins. In particular, the systematic screening with a series of overlapping fragments, called epitope mapping or substitution analogues, needs short peptides in large numbers although, in general, micro molar quantities are sufficient. In this regard, the value of using synthetic peptides as probes in biochemistry and pharmacology is comparable to the value of oligonucleotides in molecular biology. The systematic use of peptides, however, has been limited by the cost, time and special expertise or equipment required to provide a significant number of peptides for evaluation. Therefore, BSI over the past several years has developed synthesis platforms that are capable of the simultaneous synthesis of many peptides with FLEXIBILITY, SPEED, and HIGH THROUGHPUT at an economic price, resulting in a great value to our customers.

Peptide Libary Design Tool

Bio-Synthesis has implemented peptide libary tools to its rapid high-throughput parallel peptide synthesis platform. These libraries can be used to screen highly active compounds such as antigenic peptides, receptor ligands, antimicrobial compounds, and enzyme inhibitors. Some of the applications of peptide screening tools are as follows:
  • Epitope mapping studies.
  • Vaccine research.
  • High-throughput protein interaction analysis.
  • Customized peptide microarray production.
  • Kinase assays.
These six powerful peptide library generation tools provide client with the ability to generate large numbers of screening peptide which involves epitope mapping, sequence optimzation, and sequence stabilization. Epitope mapping requires the construction of overlapping peptide libraries, which can be customized by adjusting the fragment length and offset number for the optimum balance between low costs and high data value. In addition to overlapping peptide libaries, Bio-Synthesis offer five additional systematic peptide libary screening service tools featuring different strategies for sequence optimization.

Alanine Peptide Scanning Library: The generation of peptide library in which alanine (Ala, A) is systematically substituted into each of the amino acids which can be used to identify epitope activity.

Positional Peptide Library: A selected position in a peptide sequence is systematically replaced with different amino acid to show the effect on the substitute amino acid at certain position.

Truncation Pepitde Library: The truncation libary is been used to predict the minimum amino acid length required for optimum epitope activity.

Random Peptide Library: It's constructed by substituting selected positions on the original peptide randomly and simultaneously with all other natural amino acids in a shot gun approach with a purpose to elucidate potential alternatives for enhanced peptide activity.

Scramble Peptide Library: Scramble Library is constructed by carrying out permutation on the original peptide's sequence. It has the potential to give all possible alternatives and offers and represents the highest degree of variability for peptide library.

Although phylogenetically similar to this subfamily, Caspase-2 is thought to be involved in stress-induced apoptosis (5). Caspase-2 has two major isoforms; overexpression on the long form results in apoptosis while that of the short form suppresses cell death (6).
