CD21 Matched ELISA Antibody Pair Set,Human General Information
CD21 Matched ELISA Antibody Pair Set,Human
Solid Phase Sandwich ELISA
Quantitative determination of Human CD21
1. Capture Antibody 1.0 mg/mL of rabbit anti-CD21 monoclonal antibody. Dilute to a working concentration of 2 μg/mL in CBS before coating. (Catalog: # 10811-R019)
2. Detection Antibody 0.25 mg/mL rabbit anti-CD21 monoclonal antibody conjugated to horseradish-peroxidase (HRP). Dilute to working concentration of 0.25 μg/mL in detection antibody dilution buffer before use. (Catalog: # 10811-R001)
3. Standard Each vial contains 70 ng of recombinant CD21. Reconstitute with 1 mL detection antibody dilution buffer. After reconstitution, store at -20℃ to -80℃ in a manual defrost freezer. A seven-point standard curve using 2-fold serial dilutions in sample dilution buffer, and a high standard of 2 ng/mL is recommended.

CD21 Background Information
The cluster of differentiation (CD) system is commonly used as cell markers in immunophynotyping. Different kinds of cells in the immune system can be identified through the surface CD molecules which associating with the immune function of the cell. There are more than 320 CD unique clusters and subclusters have been identified. Some of the CD molecules serve as receptors or ligands important to the cell through initiating a signal cascade which then alter the behavior of the cell. Some CD proteins do not take part in cell signal process but have other functions such as cell adhesion. CD21, also known as Complement component (3d / Epstein Barr virus) receptor 2 and CR2, is a member of the CD system and is a protein involved in complement system. CD21 is present on all mature B-cells and some T-cells and follicular dendritic cells. CD21 on mature B-cells form a complex called the B cell receptor complex with two other membrane proteins, CD19 and CD81. CD21 has a function in the complement system through serving as the cellular receper specific for ligands such as C3 and C4 which can be attached to foreign macromolecules in order to remove or uptake them. This results in B-cells having enhanced response to the antigen.
