Cat.No. : VTCN1-429H
Product Overview : Biotinylated Human B7-H4 is expressed from HEK293 cells. It contains AA Phe 29 - Ala 258 (Accession # NP_078902). This protein carries a polyhistidine tag at the C-terminus.
Source : HEK293
Species : Human
Tag : His
Predicted N Terminal : Phe 29
Form : Lyophilized from 0.22 um filtered solution in PBS, pH7.4, 10% trehalose.
Bio-activity : Immobilized anti-B7-H4 mAb (Human IgG1) at 2 ug/mL can bind Biotinylated Human B7-H4 with a linear range of 4-62 ug/mL.
Molecular Mass : The protein has a calculated MW of 26.1 kDa. The protein migrates as 43-60 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 : >95% as determined by SDS-PAGE.
Characteristic : The primary amines in the side chains of lysine residues and the N-terminus of the protein are conjugated with biotins using standard chemical labeling method. A standard biotin reagent (13.5 angstroms) is used in this product. The biotin to protein ratio is 0.7-1 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.
