CD11a (LFA-1alpha) Monoclonal Antibody (HI111), Functional Grade, eBioscience™, Invitrogen™

Description

The HI111 monoclonal antibody reacts with human CD11a, the 180 kDa integrin alphaL, also known as the lymphocyte function associated antigen-1 (LFA-1) alpha chain. LFA-1, formed by non-covalent association of CD11a with CD18 (integrin beta2), serves as an important adhesion molecule involved in lymphocyte and granulocyte function. CD54 (ICAM-1), CD102 (ICAM-2), and CD50 (ICAM-3) are ligands for LFA-1. CD11a is expressed by all leukocytes. Applications Reported: The HI111 antibody has been reported for use in flow cytometric analysis. It has also been reported in blocking of CD11a function in mixed lymphocyte reactions. Applications Tested: The HI111 antibody has been tested by flow cytometric analysis of normal human peripheral blood cells. This can be used at less than or equal to 1 μg per test. A test is defined as the amount (μg) of antibody that will stain a cell sample in a final volume of 100 μL. Cell number should be determined empirically but can range from 10^5 to 10^8 cells/test. It is recommended that the antibody be carefully titrated for optimal performance in the assay of interest. Storage and handling: Use in a sterile environment. Filtration: 0.2 μm post-manufacturing filtered. Purity: Greater than 90%, as determined by SDS-PAGE. Endotoxin Level: Less than 0.001 ng/ μg antibody, as determined by LAL assay. Aggregation: Less than 10%, as determined by HPLC.
