Species : Human
Source : Human Cells
Tag : Fc&His
Protein Length : 1-242 a.a.
Form : Lyophilized from sterile PBS, pH 7.4
Molecular Mass : The recombinant human B7-1/Fc is a disulfide-linked homodimeric protein. The reduced monomer consists of 455 amino acids and predicts a molecular mass of 51.7 kDa. By SDS-PAGE, the apparent molecular mass of rh B7-1/Fc is approximately 80-90 kDa due to the glycosylation.
Endotoxin : < 1.0 eu per μg of the protein as determined by the LAL method.
Stability : Samples are stable for up to twelve months from date of receipt at -70oC.
Storage : Store it under sterile conditions at -20oC~-70oC. It is recommended that the protein be aliquoted for optimal storage. Avoid repeated freeze-thaw cycles.
Reconstitution : It is recommended that sterile water be added to the vial to prepare a stock solution. Centrifuge the vial at 4℃ before opening to recover the entire contents.

Article Snippet:ICAM-1 liposomes were mixed with DOPC/CAP-biotin-PE liposomes containing 1 mol% DGS-NTA-Ni at a 2:1 ratio and deposited onto piranha-treated cover glass mounted on a 35 mm dish.ICAM-1 liposomes were mixed with DOPC/CAP-biotin-PE liposomes containing 1 mol% DGS-NTA-Ni at a 2:1 ratio and deposited onto piranha-treated cover glass mounted on a 35 mm dish.. Lipid bilayers on the glass were blocked with 1% BSA and loaded sequentially with Alexa488-labeled streptavidin (1 μg/ml) and mono-biotinylated I-A b with 0.1 M OVA peptide (AAHAEINEA) obtained through the NIH Tetramer Core Facility (Atlanta, GA) and CD80-histidine tag (Creative BioMart, Shirley, NY).. Densities of ICAM-1 (250 molecules/μm 2 ) and CD80 (90 molecules/μm 2 ) were measured as described [ ], and supported pMHC-dependent attachment and IS formation on lipid bilayers.Densities of ICAM-1 (250 molecules/μm 2 ) and CD80 (90 molecules/μm 2 ) were measured as described [ ], and supported pMHC-dependent attachment and IS formation on lipid bilayers.
