Introduction
The CD21 protein is found on mature B cells, follicular dendritic cells, and in lower amounts on immature thymocytes and T lymphocytes. During B cell development, CD21 appears after the pre-B cell stage, remains throughout peripheral B cell development, and disappears when the cells become plasma cells. When B cells are stimulated in vitro, CD21 expression is gradually lost. CD21 functions as a receptor for Complement components C3d, C3dg, and iC3b, for EBV, and for IFNalpha. CD21 binds to CD23 and associates with CD19, CD81, and Leu13 to form a large signal-transduction complex that is involved in B cell activation.
Formulation
The antibody is supplied as a 1 mg/ml solution in PBS after reconstitution.
Storage Procedures
The lyophilized antibody should be stored at 4 degrees Celsius. After reconstitution, the antibody should be used within one month. If it is not intended for use within one month, it should be aliquoted and stored at -20 degrees Celsius.
Solubility
Reconstitute the antibody with the appropriate volume of H2O. Mix gently by inverting the vial several times, then wash the sides of the vial with the reconstituted antibody. Wait 30-60 seconds before use.
Applications
This antibody is suitable for staining applications. The recommended concentration for staining is 10 µl of antibody per 1,000,000 cells.
Available Conjugates
This antibody is also available conjugated to biotin and FITC. For staining with biotin or FITC-conjugated antibody, use 5-10 µl of antibody per 1,000,000 cells.

Product Science Overview
Function and Importance
CD21 is part of a larger signal-transduction complex that includes CD19, CD81, and Leu13 . This complex is essential for amplifying B-cell activation and proliferation, which is a critical aspect of the adaptive immune response . The interaction of CD21 with its ligands enhances antibody production and helps in the efficient clearance of pathogens .
Mouse Anti-Human CD21 Antibodies
Mouse anti-human CD21 antibodies are monoclonal antibodies developed in mice that specifically target the human CD21 protein. These antibodies are widely used in various scientific applications, including:
Applications in Research
The use of mouse anti-human CD21 antibodies has been instrumental in advancing our understanding of the immune system. These antibodies have been used to study:
- B-cell activation and proliferation: By examining how CD21 interacts with other components of the immune system .
- Pathogen interactions: By investigating how pathogens like EBV exploit CD21 to infect host cells .
- Immune disorders: By exploring the role of CD21 in autoimmune diseases and other immune-related conditions .
