    Sino biological qEASY qPCR primer pairs are used for SYBR Green-based real-time RT-PCR, The primers are designed by using SBI's proprietary primer design algorithm. Our primer collection covers the entire human genomes. It can be widely applied in the quantitative analysis of gene expression.

    Unique Primer Design

    To avoid genomic DNA amplification, at least one primer is designed crosses the junction of exons according to the conserved region of a specific gene with all variants.

    Strict Validation Process

    Confirmed in positive organizations; screened the primer with high specificity and high sensitivity.

    Uniform PCR conditions, Saving time and cost

    ~100% amplification curve, ensuring the accuracy of the RNA quantitative

    PD-L1/B7-H1/CD274 Background

    Programmed death-1 ligand-1 (PD-L1, CD274, B7-H1) has been identified as the ligand for the immunoinhibitory receptor programmed death-1(PD1/PDCD1) and has been demonstrated to play a role in the regulation of immune responses and peripheral tolerance. PD-L1/B7-H1 is a member of the growing B7 family of immune molecules and this protein contains one V-like and one C-like Ig domain within the extracellular domain, and together with PD-L2, are two ligands for PD1 which belongs to the CD28/CTLA4 family expressed on activated lymphoid cells. By binding to PD1 on activated T-cells and B-cells, PD-L1 may inhibit ongoing T-cell responses by inducing apoptosis and arresting cell-cycle progression. Accordingly, it leads to growth of immunogenic tumor growth by increasing apoptosis of antigen specific T cells and may contribute to immune evasion by cancers. PD-L1 thus is regarded as promising therapeutic target for human autoimmune disease and malignant cancers.
