Product Name :
Mouse anti Human CD42a

Description :
| Clone ESS | Isotype IgG1 | Product Type Monoclonal Antibody | Units 100 µg | Host Mouse | Species Reactivity Human | Application Flow Cytometry

Background :

Source :
CD42a or Platelet glycoprotein IX (GP9) is a small, single-chain membrane glycoprotein of 22 kDa found on the surface of human platelets. It forms a noncovalent complex with CD42b, CD42c and CD42d (GPIbα, GPIbβ, and GPV). The GPIb-IX-V complex is the platelet receptor for von Willebrand factor and is known as von Willebrand’s factor-dependent adhesion receptor. The CD42a expression is restricted to platelets and megakaryocytes and as a result the Mouse anti Human CD42a antibody reacts with resting and activated platelets, and weakly on monocytes and megakaryocytes. Synonyms: CD42a <

Applications :
Flow Cytometry Consult the appropriate Exalpha Negative Control factsheet to determine the amount of antibody to be used as a control for Platelets. Collect blood aseptically by venipuncture into an ACD or EDTA blood collection tube. Important: Within 5 minutes of blood collection, fix blood sample by placing 100 ?l of blood in test tube containing 1 ml of cold (4°C) 1X PBS with 1% paraformaldehyde. Mix by vortexing. Centrifuge the fixed blood at 1200 x g for 5 minutes at room temperature (RT) 20°C. Aspirate the supernatant, leave pellet. Prior to staining, wash the fixed blood pellet 2X with 1 ml 1X PBS + 0.1% Azide at RT. Centrifuge the fixed blood at 1200 x g for 5 minutes at room temperature (RT) 20°C. Aspirate the supernatant, leave pellet. Resuspend the pellet in 1 ml of 1X PBS at RT. To a clean labeled test tube add 10 ?l of Exalpha monoclonal antibody. Carefully add 50 _l of the fixed blood suspension to the bottom of the test tube. Vortex and incubate at room temperature for at least 15 minutes and analyzed within 3 hours. Please note: Using this procedure will yield twenty samples for platelet analysis. Select logarithmic (Log) amplification for both Forward (FSC) and Side (SSC) scatters, while collecting data for platelets. See instrument manufacturer’s instructions for Immunofluorescence analysis with a flow cytometer or microscope. Functional Analysis: Flow Cytometry Staining

Antibodies are immunoglobulins secreted by effector lymphoid B cells into the bloodstream. Antibodies consist of two light peptide chains and two heavy peptide chains that are linked to each other by disulfide bonds to form a “Y” shaped structure. Both tips of the “Y” structure contain binding sites for a specific antigen. Antibodies are commonly used in medical research, pharmacological research, laboratory research, and health and epidemiological research. They play an important role in hot research areas such as targeted drug development, in vitro diagnostic assays, characterization of signaling pathways, detection of protein expression levels, and identification of candidate biomarkers.
