qPCR (Quantitative PCR)即定量PCR,也称实时荧光定量PCR或实时定量PCR (Real-time quantitative PCR)、实时PCR (Real-time PCR),是一种在DNA扩增反应过程中,以荧光定量测定每个聚合酶链式反应(PCR)循环后产物总量的方法。qPCR常用的两种方法是SYBR Green等荧光染料法和探针法。SYBR Green等荧光染料法是使用带有荧光的...

After 88 and 132 hours of IVC, no significant alterations in either mRNA or protein levels of Cx43 and Cdk4 were found. Cx43 and Cdk4 were localized in the cell nucleus before IVC, whereas after 44, 88, and 132 hours of IVC, both proteins translocated to the cytoplasm. In cumulus-...
On the vaccine side, manufacturers are trying a multi-pronged approach to stimulate the immune system by using both traditional approaches (i.e., protein subunits, inactivated viruses, and virus-like particles) and novel platforms that are based on delivery o...
Three other siblings, 2, 3, and 4, also had discrepant DNA and phenotype data and none had sickle cell-related symptoms. Such a discrepancy may arise from the preferential amplification of the βS allele in PCR, with concomitant failure to amplify the βA allele. To explore further, we ...
