MHC Class II I-Abd Mouse Monoclonal Antibody [Clone ID: 28-16-8S]

Specifications

Product Data
Clone Name	28-16-8S
Applications	FC
Recommend Dilution	Flow cytometry.
Reactivity	Mouse
Host	Mouse
Clonality	Monoclonal
Specificity	This monoclonal antibody reacts with the I-Ab encoded MHC class II antigen expressed on mouse strains of the H-2b haplotype. It also reacts with the I-Ad encoded MHC class II antigen expressed on mouse strains of the H-2d haplotype. Class II antigens are most highly expressed on antigenpresenting cells including B cells, macrophages, dendritic cells and certain epithelial cells.
Formulation	PBS and contains 0.02% sodium azide (NaN3) as a preservative. Label: Biotin State: Liquid purified IgM
Concentration	lot specific
Purification	Affinity 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.
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 0.2µg – 0.5mg* 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). Results - Tissue Distribution by Flow Cytometry Analysis: Mouse Strain: BALB/c Cell Concentration: 1x10e6 cells per test Antibody Concentration Used: 0.5 µg/10e6 cells Isotypic Control: Biotin Mouse IgM
