SARS Spike Antibody


A novel coronavirus has recently been identified as the causative agent of SARS (Severe Acute Respiratory Syndrome) (1-2). Coronaviruses are a major cause of upper respiratory diseases in humans (3). The genomes of these viruses are positive-stranded RNA approximately 27-31kb in length. SARS infection can be mediated by the binding of the viral spike protein, a glycosylated 139 kDa protein and the major surface antigen of the virus, to the angiotensin-converting enzyme 2 (ACE2) on target cells. This binding can be blocked by a soluble form of ACE2 (4).

Additional Names: SARS Spike (IN3), SARS

Source:SARS Spike antibody was raised against a synthetic peptide corresponding to amino acids near the center of the SARS Spike glycoprotein.
Purification: Affinity chromatography purified via peptide column
Clonality and Clone: This is a polyclonal antibody.
Host: SARS Spike antibody was raised in rabbit.

Please use anti-rabbit secondary antibodies.
Immunogen: Human SARS Spike (Intermediate Domain 3) Peptide (Cat. No. 3225P)
Application: SARS Spike (IN3) antibody can be used for the detection of SARS Spike protein in ELISA. It will detect 10 ng of free peptide at 1 µg/ml.Other applications are pending.
Tested Application(s): E
Buffer: Antibody is supplied in PBS containing 0.02% sodium azide.
Blocking Peptide:Cat. No. 3225P - SARS Spike (IN3) Peptide

Hi all,

Severe acute respiratory syndrome or SARS is a respiratory disease in humans which is caused by the SARS coronavirus. It is not claimed to have been eradicated, as it may still be present in its natural host reservoirs and may potentially return into the human population in the future. Thanks a lot!
