Invitrogen™ MHC Class II Monoclonal Antibody (OX17), PerCP-eFluor™ 710, eBioscience™

Description

Description: This OX17 monoclonal antibody reacts with the I-E molecule of rat MHC Class II, which is also known as RT1-D. MHC Class II is expressed on antigen presenting cells such as B cells, dendritic cells, and macrophages. The OX17 antibody has been reported to possess blocking activity. Moreover, crossblocking studies suggest that OX17 and HIS19 recognize different epitopes. Applications Reported: This OX17 antibody has been reported for use in flow cytometric analysis. Applications Tested: This OX17 antibody has been tested by flow cytometric analysis of rat splenocytes. This can be used at less than or equal to 0.25 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. PerCP-eFluor® 710 emits at 710 nm and is excited with the blue laser (488 nm); it can be used in place of PerCP-Cyanine5.5. We recommend using a 710/50 bandpass filter, however, the 695/40 bandpass filter is an acceptable alternative. Please make sure that your instrument is capable of detecting this fluorochrome. Fixation: Samples can be stored in IC Fixation Buffer (Product # 00-8222) (100 μL cell sample + 100 μL IC Fixation Buffer) or 1-step Fix/Lyse Solution (Product # 00-5333) for up to 3 days in the dark at 4...

MHC (major histocompatibility complex) class II molecules are transmembrane glycoproteins expressed on the surface of professional antigen-presenting cells, such as macrophages, dendritic cells and B cells. Before their exposition on the cell surface, the MHC class II molecules react with endocytosed exogenous antigens, which are then presented to the T cells. The antigen-binding grove between MHC class II alpha and beta chain is open at both ends and is 15-24 amino acid residues long. HLA and MHC antibodies play a significant role in Immunopeptidomics, facilitating the identification and characterization of neoantigens through high-performance liquid chromatography coupled to tandem Mass Spectrometry.
