Specifications

Programmed Death-Ligand 1 (PD-L1), also known as CD274 or B7 Homolog 1 (B7-H1), is a transmembrane protein involved in suppressing the immune system and rendering tumor cells resistant to CD8 T cell-mediated lysis through binding of the Programmed Death-1 (PD-1) receptor. Overexpression of PD-L1 may allow cancer cells to evade the actions of the host immune system. In renal cell carcinoma, upregulation of PD-L1 has been linked to increased tumor aggressiveness and risk of death, and, in ovarian cancer, higher expression of this protein has lead to significantly poorer prognosis. PD-L1 has also been linked to systemic lupus erythematosus and cutaneous melanoma. When considered in adjunct with CD8 tumor-infiltrating lymphocyte density, expression levels of PD-L1 may be a useful predictor of multiple cancer types, including stage III non-small cell lung cancer, hormone receptor negative breast cancer, and sentinel lymph node melanoma.

Description

The ExcelTaq™ 5X Fluorescent PCR Master Mix is a ready-to-use mixture for amplifying targeted DNA fragments. It is designed to serve as a master mix for virtually all PCR applications. This product is supplied as a 5X concentrated mixture containing all the essential ingredients for PCR with the exception of templates and primers. In addition, the mixture contains electrophoresis tracking dye (Bromophenol blue) and a safer fluorescent DNA staining dye, which enables the user to track the electrophoresis process in real time as well as eliminates the need for the staining process. The resultant PCR reaction mixture is sufficiently dense enough to be loaded directly into a TAE or TBE buffered gel for electrophoresis.

Features

• 5’→3’ DNA polymerase activity
• No detectable 3’→5′ exonuclease (proofreading) activity
• Generates PCR products with 3′-dA overhangs
• High yield PCR 
• High reproducibility
• Reduced  pipetting errors
• For direct loading into electrophoresis analysis
• DNA bands can be visualized directly under UV or 470 nm blue light illumination

Applications 

• Routine PCR
• Colony PCR
• High throughput PCR
• Amplification of DNA fragments up to 8 kb
• Generation of PCR products for TA cloning
