For rapid and efficient concentration and desalting of protein samples
* Protein recovery of up to 99%
* Up to 99% removal of salts
* Fast processing time, rapid spin-column format
The ProteoSpin™ CBED Micro Kit provides a fast and a simple procedure for concentration, buffer exchange and desalting of protein samples based on spin column technoloy. The ProteoSpin™ CBED Micro Kit comes with solutions for concentrating and desalting both acidic and basic proteins. Two procedures, one for acidic proteins and another for basic proteins, are provided.
The kit employs a proprietary matrix, which acts as an ion exchanger and is able to concentrate proteins many fold as well as remove salts. Breifly, pH Binding Buffer is added to the protein sample and the sample is applied to Bio-Synthesis's column (BIND). Under these conditions the proteins will bind to the column while salts and other contaminants are removed in the flowthrough. The bound proteins are then washed to remove any remaining impurities (WASH). Lastly, the clean proteins are eluted into a small volume of the provided Elution Buffer or into other optional elution buffers (user-provided) (ELUTE). Please see the procedure flowchart to the right.
One major advantage to this kit is there is no molecular weight cut-off, unlike products from other vendors. A broad size range of proteins, from peptides to antibodies can be processed. Salts such as MgCl2, NaCl, KCl, CaCl2, LiCl, and CsCl have poor affinities for Bio-Synthesis's proprietary resin and are easily removed from the sample. Another advantage over other vendor products is that the ProteoSpin™ CBED Micro Kit concentrates, removes salts and offers buffer exchange at the same time, whereas other products including dialysis do these processes as separate procedures. The ProteoSpin™ CBED Micro Kit therefore saves considerable time and expense.
Each spin column can process up to 50 µg of protein in up to 5 mL of solution. The kit can efficiently process 12 samples in only 20 minutes using an easy-to use protocol. The percentage of protein recovery is up to 99%, whereas the percentage of salt removal is up to 99%. The kit allows for the concentration of either basic or acidic proteins separately The concentrated proteins are ready for any downstream proteomic applications including 2D SDS-PAGE, Whole protein mass spectrometry, Isoelectric focusing, X-ray crystallography, NMR spectroscopy and Protein microarrays
