CD93 (AA4.1) Monoclonal Antibody (AA4.1), APC, eBioscience™, Invitrogen™

Rat Monoclonal Antibody

Supplier:  Invitrogen 17589281

Catalog No. 50-152-36

Description

Description: The AA4.1 monoclonal antibody reacts with mouse C1qRp, an approximately 130-140 kDa C-type lectin-like type I transmembrane protein. The AA4.1 antigen was originally identified as an antigen expressed on early stages of B cell development in bone marrow. Adult spleen and fetal liver also have detectable numbers of AA4.1^+ cells. In combination with other markers of hematopoietic progenitor cells such as Thy-1, Sca-1, c-Kit, CD43, and CD24, the bone marrow Lymphoid-Committed Progenitors (CLP) can be segregated into more primitive and more differentiated subsets based on expression of AA4.1. Correlated expression of surface IgM (sIgM), CD23, and AA4.1 antigen has also been used to define three nonproliferative subpopulations of immature/transitional peripheral B cells designated: T1 (AA4.1^+/CD23^-/sIgMhi), T2 (AA4.1^+/CD23^+/sIgMhi), and T3 (AA4.1^+/CD23^+/sIgMlo). AA4.1 is also reported to be expressed in cytoplasmic vesicles in endothelial cells, megakaryoblasts, and platelets. It is reported that monoclonal antibodies AA4.1 and 493 recognize different epitopes of the same molecule. Applications Reported: The AA4.1 antibody has been reported for use in flow cytometric analysis. Applications Tested: The AA4.1 antibody has been tested by flow cytometric analysis of mouse bone marrow and splenocyte cells. This can be used at less than or equal to 0.125 μg per test.

The protein encoded by this gene is a cell-surface glycoprotein and type I membrane protein that was originally identified as a myeloid cell-specific marker. The encoded protein was once thought to be a receptor for C1q, but now is thought to instead be involved in intercellular adhesion and in the clearance of apoptotic cells. The intracellular cytoplasmic tail of this protein has been found to interact with moesin, a protein known to play a role in linking transmembrane proteins to the cytoskeleton and in the remodelling of the cytoskeleton.
