Other Tags and Version Biotin & Other Labeled Version
This protein carries a polyhistidine tag at the C-terminus, followed by an Avi tag (Avitag™).
The protein has a calculated MW of 64.4 kDa. The protein migrates as 130-180 kDa when calibrated against Star Ribbon Pre-stained Protein Marker under reducing (R) condition (SDS-PAGE) due to glycosylation.
Labeling
Biotinylation of this product is performed using Avitag™ technology. Briefly, the single lysine residue in the Avitag is enzymatically labeled with biotin.
Protein Ratio
Passed as determined by the HABA assay / binding ELISA.
Purity
>95% as determined by SDS-PAGE.
Formulation
Lyophilized from 0.22 μm filtered solution in PBS, pH7.4 with trehalose as protectant.

LikesThe technical team was quick to respond to my question regarding my experimental plan to use the biotinylated CD45 PTPRC protein. The biotinylated protein was immobilized on the SA biosensor of Octet BLI R8 to measure the binding affinity of anti-human CD45RA antibody. The assay worked on the first try!
- L***h2021-12-13 LikesDear Sir or Madam, I had an overall good service from Acro Biosystems. Shipment was fast and product quality was good. Got the protocol for QC after asking the customer service. Protocol for QC was easy to understand and repeat. Easy way to download the Certificate of Analysis via the printed QR code on product vials. Customer service answered very fast and was very friendly. QC of biotinylated human CD45 protein vs. Human Galectin-1 protein (GA1-H4113) was fine. Biotinylated human CD45 protein worked fine and could be loaded on Streptavidin biosensors (Octet system).
