CD35 Antibody

SKU: orb2637678

Description

This antibody recognizes a protein of 210-220 kDa, which is identified as the complement receptor 1 (CR1), or CD35. The antibody is specific for a site on CD35 that is distal from the C3b-binding site, so that it is unable to block CD35 activity. The CD35 antibody is highly specific and shows no cross-reaction with CR2. The primary function of CD35 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 antibody labels follicular dendritic cells and follicular dendritic cell sarcoma.

Images & Validation

• Tested Applications: IHC-P
• Dilution Range: The prediluted format is supplied in a dropper bottle and is optimized for use in IHC. After epitope retrieval step (if required), drip mAb solution onto the tissue section and incubate at RT for 30 min.
• Reactivity: Human
• Application Notes:
  The concentration stated for each application is a general starting point. Variations in protocols, secondaries and substrates may require the antibody to be titered up or down for optimal performance.1. Staining of formalin-fixed tissues requires boiling tissue sections in 10mM citrate buffer, pH 6.0, for 10-20 min followed by cooling at RT for 20 minutes.2. The prediluted format is supplied in a dropper bottle and is optimized for use in IHC. After epitope retrieval step (if required), drip mAb solution onto the tissue section and incubate at RT for 30 min.
