Product Overview

Tag	His
Host Species	Human
Synonym	CD79b Molecule, CD79B Antigen (Immunoglobulin-Associated Beta), CD79b Molecule, Immunoglobulin-Associated Beta, Immunoglobulin-Associated B29 Protein, B-Cell-Specific Glycoprotein B29, Ig-Beta, IGB, B29, B-Cell Antigen Receptor Complex-Associated Protein Beta Chain, CD79b Antigen, CD79B, AGM6.
Background	CD79B is a 36 kDa trans membrane glycoprotein belonging to the immunoglobulin superfamily. Heterodimers of CD79A and CD79B connect with a membrane attached immunoglobulin on the B cell surface to create the B cell antigen receptor complex (BCR). CD79A and CD79B are essential for BCR-mediated signaling and subsequently for the development and activation of B lineage cells.
Description	CD79B Human Recombinant expressed in Sf9 Baculovirus cells is a single, glycosylated polypeptide chain containing 140a.a. (29-159a.a.) and having a molecular weight of 16.3kDa (Molecular size on SDS-PAGE will appear at approximately 18-28 kDa).CD79B is expressed with a 9a.a. His tag at C-Terminus and purified by unique purification methods.
Source	Sf9

Purity	>90.0% as determined by SDS-PAGE.
Endotoxin	<1.0 EU per μg by the LAL method.
Formulation	CD79B protein solution (0.5mg/ml) contains Phosphate Buffered Saline (pH 7.4) and 10% glycerol.
Stability	Recombinant protein is stable for 12 months at -70°C
Usage	For Research Use Only
Storage	Store at 4°C if entire vial will be used within 2-4 weeks. Store, frozen at -20°C for longer periods of time. For long term storage it is recommended to add a carrier protein (0.1% HSA or BSA).Avoid multiple freeze-thaw cycles.

Proteins are sensitive to heat, and freeze-drying can preserve the activity of the majority of proteins. It improves protein stability, extends storage time, and reduces shipping costs. However, freeze-drying can also lead to the loss of the active portion of the protein and cause aggregation and denaturation issues. Nonetheless, these adverse effects can be minimized by incorporating protective agents such as stabilizers, additives, and excipients, and by carefully controlling various lyophilization conditions.

Commonly used protectant include saccharides, polyols, polymers, surfactants, some proteins and amino acids etc. We usually add 8% (mass ratio by volume) of trehalose and mannitol as lyoprotectant. Trehalose can significantly prevent the alter of the protein secondary structure, the extension and aggregation of proteins during freeze-drying process; mannitol is also a universal applied protectant and fillers, which can reduce the aggregation of certain proteins after lyophilization.

Our protein products do not contain carrier protein or other additives (such as bovine serum albumin (BSA), human serum albumin (HSA) and sucrose, etc., and when lyophilized with the solution with the lowest salt content, they often cannot form A white grid structure, but a small amount of protein is deposited in the tube during the freeze-drying process, forming a thin or invisible transparent protein layer.

Reminder: Before opening the tube cap, we recommend that you quickly centrifuge for 20-30 seconds in a small centrifuge, so that the protein attached to the tube cap or the tube wall can be aggregated at the bottom of the tube. Our quality control procedures ensure that each tube contains the correct amount of protein, and although sometimes you can't see the protein powder, the amount of protein in the tube is still very precise.
