Human LSelectin (Leukocyte Selectin, LAM1,LECAM1,LECCAM1,TQ1, Leu8,MEL14 antigen, DREG, lymph node homing receptor, CD62L), a member of the Selectin family, is a cell surface glycoprotein expressed constitutively on a wide variety of leukocytes.

Protein Details

>97% by SDS Page and analyzed by silver stain.
Endotoxin Level
<1.0 EU/µg as determined by the LAL method
Biological Activity
Recombinant Human L-Selectin was measured by its ability of the immobilized protein to support the adhesion of LS180 human colorectal adenocarcinoma cells. When 5 x 104 cells/well are added to human LSelectin coated plates (10 μg/mL with 100 μL/well), >50% will adhere after 1 hour incubation at 37 °C.

State of Matter
Predicted Molecular Mass
The predicted molecular weight of Recombinant Human LAM-1, LECAM-1, LECCAM-1, TQ1, Leu-8, CD62L is Mr 33.1 kDa.
Predicted Molecular Mass
This recombinant protein was 0.2 µm filtered and lyophilized from modified Dulbecco’s phosphate buffered saline (1X PBS) pH 7.2 – 7.4 with no calcium, magnesium, or preservatives. 1% sorbitol was added as a stabilizer.
Storage and Stability
This lyophilized protein is stable for six to twelve months when stored desiccated at -20°C to -70°C. After aseptic reconstitution, this protein may be stored at 2°C to 8°C for one month or at -20°C to -70°C in a manual defrost freezer. Avoid Repeated Freeze Thaw Cycles.

Applications and Recommended Usage ?
(Quality Tested by Leinco)
ELISA Sandwich: This antibody is useful as the capture antibody in a sandwich ELISA. The suggested coating concentration is 5 µg/ml (100 µl/well) µg/ml.
Flow Cytometry: PN:A106
Flow Cytometry: It is recommended to use the indirect method for signal enhancement when enumerating cells expressing CXCR5. A suggested method would be to stain cells expressing CXCR5 with approximately 10 µl per test. A typical test sample constitutes approximately 50 µl of packed whole blood or 1 x 105 continuous passage or activated cell cultures that have been centrifuged at 500 X g for five minutes. Labeling of the cells with the biotin conjugate should be followed by PN:A104, resuspended in 200-400 µl of 1X PBS.
