いいねOur team recently purchased this PD1 protein and another Fc tagged protein. We order these reagents to validate several bench mark antibodies in ELISA. The assay just done recently and the results meet the expectation. All proteins passed our in house QC. The logistic is fast, we receive the package just in few days. The shipment was packed well with no damage.- D***.2022-02-04 いいねI ordered the Human PD-1 / PDCD1 Protein, His Tag (MALS Verified) for my sample workup. This antibody gives a specific signal with a little background. This product is also very stable for long-term storage, it is still good after a year (I stored it at -40°C after opening the vial).
- Y***n2021-08-18 いいねI purchase human PD-1-his for BLI and yeast display competition assay. The product was shipped and delivered really fast. The experimental results were clean and reproducible with high consistency. The product information sheet came along with the product gave clear, detail and useful information and additional product QC information on the website is easy to find and comprehensive. I'm really satisfied with the product.
