Cd8a Rat Monoclonal Antibody [Clone ID: YTS169.4]

Specifications

Product Data
Clone Name	YTS169.4
Applications	FC, IHC
Recommend Dilution	Flow Cytometry. Immunohistochemistry on frozen sections.
Reactivity	Mouse
Host	Rat
Clonality	Monoclonal
Immunogen	Murine thymocytes
Specificity	Antibody CL007 reacts with a protein of approximately 30 kDa found on mouse thymocytes and mouse cytotoxic/ suppressor T cells. It does not bind to mouse helper/inducer T cells. It binds to T lymphocytes from all mouse strains regardless of phenotypic expression (i.e. reacts with T lymphocytes from mouse strains expressing the Ly 2.1 or Ly 2.2 phenotype). It can be used to investigate the role of T cells in models for infectious disease, autoimmunity, transplantation tolerance and fundamental aspects of immunology.
Formulation	PBS, 0.02% NaN3 and EIA grade BSA as a stabilizing protein to bring total protein concentration to 4-5 mg/ml. Label: FITC State: Liquid purified IgG
Concentration	lot specific
Purification	Protein G Chromatography
Conjugation	FITC
Storage Condition	Store the antibody at 2 - 8 °C up to one month or (in aliquots) at -20 °C for longer. Avoid repeated freezing and thawing.
Gene Name	CD8 antigen, alpha chain
Database Link	Entrez Gene 12525 Mouse UniProt ID P01731
Background	The CD8 antigen is a cell surface glycoprotein found on most cytotoxic T lymphocytes that mediates efficient cell to cell interactions within the immune system. The CD8 antigen, acting as a coreceptor, and the T cell receptor on the T lymphocyte recognize antigen displayed by an antigen presenting cell (APC) in the context of class I MHC molecules. The functional coreceptor is either a homodimer composed of two alpha chains, or a heterodimer composed of one alpha and one beta chain. Both alpha and beta chains share significant homology to immunoglobulin variable light chains.
Synonyms	CD8 alpha chain, CD8A, MAL
Note	Strain Distribution by Flow Cytometry Analysis: Procedure: see below Cell Concentration: 1x10e6 cells per test Antibody Concentration Used: 0.1 µg/10e6 cells Strains Tested: BALB/c, C57BL/6 Positive: BALB/c, C57BL/6 Negative: non Protocol: FLOW CYTOMETRY ANALYSIS: Method: 1. Prepare a cell suspension in media A. For cell preparations, deplete the red blood cell population with Lympholyte®-M cell separation medium. 2. Wash 2 times. 3. Resuspend the cells to a concentration of 2x107 cells/ml in media A. Add 50µl of this suspension to each tube (each tube will then contain 1 x 106 cells, representing 1 test). 4. To each tube, add 0.1-0.5 µg* of CL007F per 106 cells. 5. Vortex the tubes to ensure thorough mixing of antibody and cells. 6. Incubate the tubes for 30 minutes at 4°C. (It is recommended that the tubes are protected from light, since most flurochromes are light sensitive.) 7. Wash 2 times at 4°C. 8. Resuspend the cell pellet in 50 µl ice cold media B. 9. Transfer to suitable tubes for flow cytometric analysis containing 15 µl of propidium iodide at 0.5 mg/ml in PBS. This stains dead cells by intercalating in DNA. Media: A. Phosphate buffered saline (pH 7.2) + 5% normal serum of host species + sodium azide (100 µl of 2M sodium azide in 100 mls). B. Phosphate buffered saline (pH 7.2) + 0.5% Bovine serum albumin + sodium azide (100 µl of 2M sodium azide in 100 mls).
