Human SELP / selectin P / P-selectin Protein (Fc Tag)

分子别名（Synonym）:CD62,CD62P,GMP140,GRMP,LECAM3,P-Selectin,PADGEM,PSEL种属（Species）：Human表达系统（Expressed Host）：HEK293 Cells制剂（Buffer）：Lyophilized from sterile PBS, pH 7.4分子量（Molecule Mass）：The recombinant human SELP/Fc is a disulfide-linked homodimeric protein. The reduced monomer consists of 971 amino acids and has a predicted molecular mass of 107 kDa. The apparent molecular mass of the reduced monomer is approximately 130-150 kDa in SDS-PAGE under reducing conditions due to glycosylation.内毒素（Endotoxin）：＜1.0 EU per μg by the LAL method.生物活性(Activity)：Measured by the ability of the immobilized protein to support the adhesion of U937 human histiocytic lymphoma cells. When 5 x 10E4 cells/well are added to SELP/Fc Chimera coated plates (10 μg/mL with 100 μL/well), > 80% cells will adhere after 1 hour at 37℃.表达区间（Protein Construction）：A DNA sequence encoding the human SELP (AAN06828.1) extracellular domain (Ser 2-Ala 771) was fused with the Fc region of human IgG1 at the C-terminus.存储条件（Storage）：For long term storage, the product should be stored at lyophilized state at -20℃ or lower.Please avoid repeated freeze-thaw cycles. No activity loss is observed after storage at:4-8℃ for 12 months in lyophilized state;-70℃ for 3 months under sterile conditions after reconstitution.运输条件：In general, recombinant proteins are provided as lyophilized powder which are shipped at ambient temperature.Bulk packages of recombinant proteins are provided as frozen liquid. They are shipped out with blue ice unless customers require otherwise.
