Recognizes a protein of 210-220kD, which is identified as the complement receptor 1 (CR1)/CD35. This monoclonal antibody is specific for a site in CR1 that is distal from the C3b-binding site, so that it is unable to block CR1 activity. This monoclonal antibody is highly specific to CR1 and shows no cross-reaction with CR2. The primary function of CR1 is to serve as the cellular receptor for C3b and C4b, the most important components of the complement system leading to clearance of foreign macromolecules. The Knops blood group system is a system of antigens located on this protein. Follicular dendritic cells (FDC) are restricted to the B-cell regions of secondary lymphoid follicles. They are CD21+/CD35+/CD1a-. This monoclonal antibody labels follicular dendritic cells and follicular dendritic cell sarcoma.

Applications
Suitable for use in FLISA, Flow Cytometry, Western Blot, Immunofluorescence, Immunoprecipitation and Immunohistochemistry. Other applications not tested.
Recommended Dilution
Flow Cytometry: 0.5-1ug/10e6 cells Western Blot: 0.5-1ug/ml Immunoprecipitation: 1-2ug/500ug protein lysate Immunofluorescence: 1-2ug/ml Immunohistochemistry (Frozen & Formalin fixed paraffin embedded): 0.5-1ug/ml/30min @ RT Optimal dilutions to be determined by the researcher.
Positive Control
Follicular dendritic cells (FDC) in tonsil
Storage and Stability
Store product at 4°C if to be used immediately within two weeks. For long-term storage, aliquot to avoid repeated freezing and thawing and store at -20°C. Aliquots are stable at -20°C for 12 months after receipt. Dilute required amount only prior to immediate use. Further dilutions can be made in assay buffer. Caution: FITC conjugates are sensitive to light. For maximum recovery of product, centrifuge the original vial after thawing and prior to removing the cap.
Note: Applications are based on unconjugated antibody.
