Detection method: one-step real-time PCR

CE IVD diagnostic kit enables detection and quantification of b2a2 (e13a2) and b3a2 (e14a2) BCR-ABL1 MAJOR fusion gene transcript variants. The detection is based on one-step RT-qPCR using fluorescently labelled probes. The quantification is evaluated as the copy number percentage ratio of BCR-ABL1 fusion transcripts to ABL1 reference gene transcripts. The detection and quantification of both fusion and reference gene transcripts is performed in one tube.

Clinical implications

The BCR-ABL1 MAJOR fusion gene variant occurs in 95% patients with chronic myelogenous leukemia (CML) and in 25% patients with acute lymphocytic leukemia (ALL). The chromosomal aberration leads to the dysregulation of the tyrosine kinase signaling pathway and to the manifestation of the oncological disease. 

The response of the patient to the treatment and the minimal residual disease is monitored under recommendation through the quantification of the b2a2 (e13a2) and b3a2 (e14a2) BCR-ABL1 MAJOR fusion transcripts related to the reference gene transcripts. The conversion of the results into the International Scale (IS) units is enabled by using STANDARD MMR BCR-ABL MAJOR (cat. no. 3280-004), which is verified for such purpose by the National Reference Laboratory of the Institute of Hematology and Blood Transfusion, Prague.

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.

Background Probiotics are defined as live microorganisms which, when administered in adequate amounts, confer a health benefit on the host. For instance, probiotics can be used in the treatment and prevention of infections and chronic inflammatory disorders of the gastrointestinal tract. Due to their health attributes, probiotics generate considerable interest in the area of functional
