Active Recombinant Human FCGRT & B2M Protein, His-Avi/Strep II-tagged, Biotinylated

Specification :
| Source : HEK293 | Species : Human | Tag : His-Avi/Strep II | Predicted N Terminal : Ala 24(FCGRT) & Ile 21(B2M) | Form : Lyophilized from 0.22 um filtered solution in PBS, pH7.4, 10% trehalose. | Bio-activity : Immobilized Yervoy Ipilumimab at 10 ug/mL (100 uL/well) can bind Biotinylated Human FcRn, His Tag, Strep Tag with a linear range of 20-625 ug/mL. | Molecular Mass : The protein has a calculated MW of 34.1 kDa (FCGRT), 13.1 kDa (B2M). The protein migrates as 38 kDa (FCGRT), 14 kDa (B2M) respectively on a SDS-PAGE gel under reducing condition due to glycosylation. | Endotoxin : | Purity : >95% 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 0.5-1 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 4℃ before opening to recover the entire contents. | Official Symbol : FCGRT; B2M | Synonyms : FcRn, FCGRT & B2M
