Database Link	Entrez Gene 20343 Mouse UniProt ID P18337
Background	L-selectin is expressed on most T and B lymphocytes, neutrophils, monocytes, eosinophils.1 Pre-incubation of lymphocytes with this antibody completely and specifically blocks binding of lymphocytes to high endothelial venules (HEV) in vitro 2,3,6 and the migration of lymphocytes to lymph nodes in vivo.2,3 Polymorphonuclear cells preincubated with this antibody do not migrate to the inflammatory foci.
Synonyms	SELL, LNHR, LYAM1, Leu-8, TQ1, gp90-MEL, LECAM1, LAM-1
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 1x10e6 cells, representing 1 test). 4. To each tube, add 0.2 - 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. (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). Results - Tissue Distribution by: Mouse Strain: BALB/c Cell Concentration: 1x10e6 cells per test Antibody Concentration Used: 0.2 µg/10e6 cells Isotypic Control: FITC Rat IgG2a Cell Source: Percentage of cells stained above control: Thymus: 88.8% Spleen: 36.6% Lymph Node: 74.4% Strain Distribution: Cell Concentration: 1x10e6 cells per test Antibody Concentration Used: 0.2 µg/10e6 cells Strains Tested: BALB/c, CBA/J, C3H/He, C57BL/6, AKR Positive: BALB/c, CBA/J, C3H/He, C57BL/6, AKR Negative: none
