Details

Cell surface proteins play a major role in signal transduction, cell adhesion, transport and serve as diagnostic and pharmacological targets. BioVision’s Cell Surface Protein Isolation Kit provides a simple and efficient method for the isolation of cell surface proteins. In this method, cells are first labeled with Sulfo-NHS-SS-Biotin, an amine-reactive, thiol-cleavable, biotinylation reagent. Cells are subsequently lysed and the labeled cell surface proteins are isolated using Streptavidin beads. The bound proteins are then released from beads by incubating with DTT solution. Biotinylation reagent is cell-membrane-impermeable with an extended spacer arm to reduce steric hindrances associated with streptavidin binding. This convenient kit provides all the required components for optimal labeling and isolation of the cell surface proteins.

How do the kit purify the cell surface protein?
K295 isolates cell surface and membrane proteins by labeling the cells with a Biotin-linker. Cells are subsequently lysed and the labeled cell surface proteins are isolated using Streptavidin beads. The bound proteins are then released from beads by incubating with DTT solution. This convenient kit provides all the required components for optimal labeling and isolation of the cell surface proteins.
What’s the difference between k295-100 & k268-50 ?
K268 is designed to extract the total cellular membrane proteins, whereas K295 purifies plasma membrane proteins specifically.
Can the kit work on bacteria or yeast cells?
The kit has been standardized for mammalian cells only
What is the exact volume of sample required for this assay?
There is no specific volume we can recommend for the amount any sample to be used since it is completely sample concentration and quality based. You have to do a pilot expt with multiple sample volumes to determine the optimal volume which gives a reading within the linear range of the standard curve. Please refer to the citations for this product to see what other clients have used with similar sample types.
Do you have trial sizes of this kit?
Unfortunately, we do not have trial sizes of this kit available. However, if you are based in the US or Canada, we will give you a 10% off list price introductory discount on its purchase price. If you are based out of this area please contact your regional BioVision distributor.
What is the shelf life of this kit?
 BioVisions’s assay kits expire 6 months from the date of shipment. Some components of the kit may expire sooner as mentioned in the data sheet
Can we purchase individual components of this kit?
Yes, you can purchase any of the kit's components without the whole kit. Please refer to the component Cat #s mentioned on the datasheet for ordering.
Can we use an alternate buffer for sample preparation (cell lysis, sample dilutions etc)?
Our assay buffers are optimized for the reactions they are designed for. They not only contain some detergents for efficient lysis of your cells/tissue, but also contain some proprietary components required for the further reactions. Therefore, we highly recommend using the buffers provided in the kit for the best results.
