MHC Class II I-Ak Mouse Monoclonal Antibody [Clone ID: 14V.18]

Specifications

Product Data
Clone Name	14V.18
Applications	FC
Recommend Dilution	Flow Cytomtry.
Reactivity	Mouse
Host	Mouse
Clonality	Monoclonal
Immunogen	A.TL spleen Donor: A.TH Fusion Partner: P3-X63-Ag 8
Specificity	This monoclonal antibody is a cytotoxic antibody specific for cells expressing the Ia antigen coded for by the A subregion of the k haplotype. The reaction pattern of this antibody with a panel of inbred and recombinant haplotypes demonstrates that the antibody reacts with Ia.m2, a private specificity of the H-2k haplotype. This antibody can be used to quantitate or to eliminate cells bearing the I-Ak (Ia.m2) antigen.
Formulation	PBS, 0.02% NaN3 and EIA grade BSA as a stabilizing protein to bring total protein concentration to 4-5 mg/ml. Label: Biotin State: Liquid purified Ig
Concentration	lot specific
Purification	Protein G Chromatography
Conjugation	Biotin
Storage Condition	Store the antibody undiluted at 2-8°C for one month or (in aliquots) at -20°C for longer. Avoid repeated freezing and thawing.
Database Link	UniProt ID P01910
Synonyms	H2-Aa
Note	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 2x10e7 cells/ml in media A. Add 50 µl of this suspension to each tube (each tube will then contain 1 x 10e6 cells, representing 1 test). 4. To each tube, add 1.0 - 0.5 µg of this Ab per 10e6 cells. 5. Vortex the tubes to ensure thorough mixing of antibody and cells. 6. Incubate the tubes for 30 minutes at 4°C. 7. Wash 2 times at 4°C. 8. Add 100 µl of secondary antibody (Streptavidin-FITC) at a 1:500 dilution. 9. Incubate tubes at 4°C for 30 - 60 minutes (It is recommended that tubes are protected from light since most fluorochromes are light sensitive). 10. Wash 2 times at 4°C. 11. Resuspend the cell pellet in 50 µl ice cold media B. 12. 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).
