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


CHK1 / CHEK1 contains 1 protein kinase domain and belongs to the protein kinase superfamily, CAMK Ser/Thr protein kinase family, NIM1 subfamily. It is a member of checkpoint kinases (Chks). Chks Checkpoint kinases (Chks) are serine/threonine kinases that are involved in the control of the cell cycle. There are two subtypes of chks that have so far been identified, CHK1 / CHEK1 and Chk2. They are essential components to delay cell cycle progression in normal and damaged cells and can act at all three cell cycle checkpoints. Chks are activated by phosphorylation. ATR kinase phosphorylates CHK1 / CHEK1 in response to single strand DNA breaks and ATM kinase phosphorylates Chk2 in response to double strand breaks. Chks phosphorylate Cdc25 phosphatase at Ser216, which leads to Cdc25 sequestration in the cytoplasm. Chks have a role in the physiological stress of hypoxia/reoxygenation. CHK1 / CHEK1 is required for checkpoint mediated cell cycle arrest in response to DNA damage or the presence of unreplicated DNA. CHK1 / CHEK1 may also negatively regulate cell cycle progression during unperturbed cell cycles.
