>Biotinylated Human PDCD1 Protein, C-Fc, His & AVI Tagged,Super Sensitivity
This protein carries a human IgG1 Fc fragment at the C-terminus, followed by a polyhistidine tag. The Avi tag (Avitag™) is inserted in-between the Fc and his tags. The protein has a calculated MW of 44.4 kDa. The protein migrates as 50-66 kDa on a SDS-PAGE gel under reducing (R) condition due to glycosylation and 100-130 kDa under non-reducing (NR) condition.
>95% as determined by SDS-PAGE.
Lyophilized from 0.22 μm filtered solution in PBS, pH7.4. Normally trehalose is added as protectant before lyophilization.

No activity loss is observed after storage at:
Biotinylated Human PD-1, His Tag & Fc tag on SDS-PAGE under reducing (R) and no-reducing (NR) conditions. The gel was stained overnight with Coomassie Blue. The purity of the protein is greater than 95%.
Flow Cytometry assay shows that recombinant Biotinylated Human PD-1, His Tag, Fc tag (Cat No. PD1-H82F2) can bind to 293 cell overexpressing human PD-L1. The concentration of PD-1 used is 1ug/ml (Routinely tested).
FACS analysis shows that the binding of Biotinylated Human PD-1, His Tag, Fc tag to 293 overexpressing PD-L1 was inhibited by increasing concentration of neutralizing anti-PD-L1 antibody. The concentration of PD1 used is 1ug/ml. The IC50 is 0.362 ug/ml (Routinely tested).
The Biotin AviTag technology is covered by U.S. Pat. No: 5,874,239 and includes any and all materials, methods, kits and related derivatives claimed by this patent. The purchase of the Acrobiosystems’s Avitag™ proteins confers to the purchaser the limited right to use the Avitag™ technology for non-commercial, or research use, or for purposes of evaluating the Avitag™ technology.
Commercial use of the Avitag™ technology to manufacture a commercial product, or use of the Avitag™ technology to facilitate or advance research which will be applied to the development of a commercial product requires a license from Avidity, LLC. Examples of Commercial use include, but are not limited to biosensors, diagnostics, therapeutic applications, proximity assays, and drug screening assays.
