Recombinant Human BCAM

Basal cell adhesion molecule (BCAM), also known as CD239, and Lutheran blood group glycoprotein (LU) are two alternatively spliced variants of a single pre-mRNA. They are type I membrane proteins of the immunoglobulin superfamily (IgSF) sharing similar structure characteristics except for the length of their cytoplasmic tails (1). BCAM/LU has a wide tissue distribution with a predominant expression in the basal layer of the epithelium and the endothelium of blood vessel walls (2). BCAM and LU share a significant sequence similarity with the CD146 (MUC18) and CD166, and themselves are adhesion molecules that bind laminin with high affinity (3). It has been shown that BCAM expression is upregulated following malignant transformation in some cell types in vivo and in vitro, and BCAM is identified as a marker of epithelial ovarian cancers. In addition, BCAM interacts with integrin in sickle red cells, and thus may potentially play a role in vaso-occlusive episodes (4). It has been demonstrated that expression of BCAM is inversely associated with the susceptibility of cells to cell death by apoptosis (5). Overexpression of the protein or inhibition of BCAM by suitable antibodies does not influence apoptotic processes.

Lyophilized

The predicted molecular weight of Recombinant Human BCAM is Mr 83.7 kDa. However, the actual molecular weight as observed by migration on SDS-PAGE is Mr 110-120 kDa.

83.7

This recombinant protein was 0.2 µm filtered and lyophilized from modified Dulbecco’s phosphate buffered saline (1X PBS) pH 7.2 – 7.3 with no calcium, magnesium, or preservatives.

This lyophilized protein is stable for six to twelve months when stored desiccated at -20°C to -70°C. After aseptic reconstitution, this protein may be stored at 2°C to 8°C for one month or at -20°C to -70°C in a manual defrost freezer. Avoid Repeated Freeze Thaw Cycles. See Product Insert for exact lot specific storage instructions.
