Co-inhibitor B7-H1 expresses in various cancers and contributes to cancer immune evasion by inhibiting T cell activation and proliferation, yet the regulatory mechanisms for B7-H1 over-expression in cancers remain largely unknown. Here, the expression of B7-H1 and PTEN proteins were firstly detected by using immunohistochemistry method. B7-H1(More)
Allele-specific amplification on the basis of polymerase chain reaction (PCR) has been widely used for single-nucleotide polymorphism (SNP) genotyping. However, the extraction of PCR-compatible genomic DNA from whole blood is usually required. This process is complicated and tedious, and is prone to cause cross-contamination between samples. To facilitate(More)
