SYBR Green Dye Method of qPCR

Excessive SYBR Green fluorescent dye is added into PCR reaction system. SYBR Green dye binding specifically to double-stranded DNA can emit fluorescence signal, but that not binding to DNA does can't. An increase of DNA products during PCR companys with an increase of fluorescence intensity and is measured at each cycle, thus allowing DNA concentrations to be quantified.

qEASY qPCR Primer Pairs and Probes

A successful qPCR assay requires efficient and specific amplification of the product. Both the primers and the target sequence can affect amplification efficiency and specificity. The use of PCR primers specifically designed and validated for qPCR assays with your target of interest is highly recommended. Sinobiological provide ready-to-use qEASY qPCR primer pairs and probes.

qEASY qPCR Primer Pairs are designed using SBI's proprietary primer design algorithm. They are used for SYBR Green dye-based real-time PCR and designed according to the conserved region of all variants of a specific gene. At least one primer crosses the junction of adjacent exons to avoid amplification of genomic DNA directly and effectively. Our primer pairs cover all genes from human, mouse, rat and can be widely applied to the quantitative analysis of gene expression. cDNA used as templates, a single, correct-size band is produced in SYBR Green dye-based PCR with each pair of primers. Therefore, our primers have the characteristics with high specificity, high amplification efficiency, wide linear range and uniform reaction conditions.

The gene expression analysis of ICAM1 in HT29 (relative quantification) by SYBR Green qPCR.

Sample description:

1. The IL17A protein factor stimulates HT29 cells to express ICAM1 for 24 hours, then the expression analysis of ICAM1 is performed.

2. The antibody for the IL17A protein suppresses HT29 cell2 to express ICAM1 for 24 hours, then the expression analysis of ICAM1 is performed.

Sample names: HT29(control),HT29(+IL17A, 24 h), HT29(+antibody for IL17A, 24h)
