gb Easy PCR Master Mix consists of hot-start Taq DNA polymerase, reaction buffer, dNTP and MgCl2. The Taq polymerase is chemically modified DNA polymerase from Thermus aquaticus. This polymerase is completely inactive at room temperature but it is rapidly activated during the initial denaturation step of PCR. The product falls into a group of TaqMan Real-Time PCR Master Mixes to provide probe-based qPCR.
gb PHARM DPYD
Detection method: allelic discrimination
The CE IVD kit is used for determination of genotype of four polymorphisms according to guidelines CPIC and DPWG: *2A (c1905+1G>A), *13 (c1679T>G), HapB3 (c1236G>A) and c2846A>T in human genomic DNA. The principle of detection is based on real-time PCR with fluorescently labelled probes (allelic discrimination).
Clinical implications of the CE IVD kit
Fluoropyrimidines (5-fluorouracil and its prodrugs capecitabine and tegafur) are the basic drugs used in chemotherapy of gastrointestinal cancer. Their use is limited by development of many toxic effects including life-threatening myelosuppression. Dihydropyrimidine dehydrogenase (DPD) catalyzes the initial step of pyrimidines catabolism.
It inactivates fluoropyrimidine chemotherapeutics and its activity influences the frequency of toxicity. It is not recommended to administer the fluoropyrimidines to the patients with DPD deficiency. When studying polymorfisms of the gene for DPD (DPYD), the relationship between presence of particular mutations and decreased activity of DPD has been demonstrated.
According to recommendations of pharmacogenetics consortia CPIC (from 2017) and DPWG (from 2019), the testing of presence of four polymorphisms in DPYD gene: *2A (c1905+1G>A), *13 (c1679T>G), HapB3 (c1236G>A) and c2846A>T is recommended before administration of the above substances. Insufficient evidence has been gathered for other polymorphisms in relation of their effect on DPD enzyme activity.
