Cat.No. : HHLA2-551H
Product Overview : Biotinylated Human B7-H7, Fc Tag, Avi Tag is expressed from HEK293 cells. It contains AA Ile 23 - Asn 344 (Accession # Q9UM44-1). This protein carries a human IgG1 Fc tag at the C-terminus, followed by a Avi tag.
Source : HEK293
Species : Human
Tag : Fc-Avi
Predicted N Terminal : Ile 23
Form : Lyophilized from 0.22 um filtered solution in 50 mM Tris, 100 mM Glycine, pH7.5, 10% trehalose.
Bio-activity : Immobilized Human CD28H, Fc Tag at 5 ug/mL (100 uL/well) can bind Biotinylated Human B7-H7, Fc Tag, Avi Tag with a linear range of 5-78 ug/mL.
Molecular Mass : The protein has a calculated MW of 65.9 kDa. The protein migrates as 80-90 kDa under reducing condition (SDS-PAGE) due to glycosylation.
Endotoxin : < 1.0 EU per μg of the protein as determined by the LAL method.
Purity : >90% as determined by SDS-PAGE.
Characteristic : Biotinylation of this product is performed using Avitag technology. Briefly, the single lysine residue in the Avitag is enzymatically labeled with biotin. The biotin to protein ratio is 0.45-1 as determined by the HABA assay.
Stability : Samples are stable for up to twelve months from date of receipt at -70ºC.
Storage : For long term storage, the product should be stored at lyophilized state at -20ºC or lower. Please avoid repeated freeze-thaw cycles. No activity loss is observed after storage at: 4-8ºC for 12 months in lyophilized state; -70ºC for 3 months under sterile conditions after reconstitution.
Reconstitution : It is recommended that sterile water be added to the vial to prepare a stock solution of 0.2 ug/ul. Centrifuge the vial at 4ºC before opening to recover the entire contents.
