|RK-10, a specific PD-L1 binding peptide|
|Three letter code||H-Gly-Ser-Gly-Ser-Gly-Ser-Thr-Tyr-Leu-Cys-Gly-Ala-Ile-Ser-Leu-Ala-Pro-Lys-Ala-Gln-Ile-Lys-Glu-Ser-Leu-NH2|
|Peptide Purity (%)||95.2|
|Additional Information||RK-10, a specific PD-L1 binding peptide, could be used for detecting PD-L1 expressing tumors with immunohistochemistry or flow cytometry. Flow cytometry was performed on cell lines and patient tissues using a fluorescent peptide (RK-10-Cy5). Immunohistochemistry using a biotin-modified peptide (RK-10-Biotin) was tested against the FDA-approved SP263 clone on biopsied patient tissues. RK-10 shows staining in the tumor regions of FFPE tissues where the SP263 kit does not. RK-10-Cy5 peptide also demonstrates PD-L1 detection in NSCLC, breast, squamous cell carcinoma, and melanoma.|
|Storage Guidelines||Ideally RK-10, a specific PD-L1 binding peptide should be stored in a freezer at or below -9C. RK-10, a specific PD-L1 binding peptide should be refrigerated after reconstitution. For more details, please refer to the manual:Handling and Storage of Synthetic Peptides|
|Terms||Please do not use the peptide for human consumption. NovoPro will immediately deny any order that we feel will be used outside of the scope of its intended purpose.|
