Abstract

The invention discloses a primer probe set, kit and method for quantitative detection of an expression level of a small integral membrane protein 3 (SMIM3) gene. The primer probe set comprises a component A and a component B; the component A includes a forward primer SMIM3-FP, a reverse primer SMIM3-RP and a probe SMIM3-probe; and the component B includes a forward primer ABL1-FP, a reverse primerABL1-RP and a probe ABL1-probe. The primer probe set, the kit and the method have the advantages that quantitative detection of the relative expression level of the SMIM3 gene in a cell is realized;moreover, the sensitivity of the SMIM3 gene and the sensitivity of an ABL1 gene both reach up to 100 copies; the sensitivity is high, results are accurate, and the reliability is high; a new auxiliarydiagnosis method or auxiliary identification method is provided for hematologic tumor cells (especially acute myelogenous leukemia and acute lymphoblastic leukemia); and the primer probe set, the kitand the method have broader application prospects.

Description

technical field [0001] The present invention relates to the field of biochemical detection, in particular to a primer probe set for quantitative detection of SMIM3 gene expression, a kit containing the primer probe set, and a method for quantitative detection of SMIM3 gene expression . Background technique [0002] Small Integral Membrane Protein 3 is SMIM3, also known as C5orf62 or NID67. The protein encoded by the SMIM3 gene is a single-chain transmembrane protein. The mRNA of SMIM3 was highest in the heart, ovary and adrenal gland, while it was only expressed at a low level in most brain regions, testis, thyroid, thymus, pituitary, kidney and intestine, and there was almost no SMIM3 in skeletal muscle and cerebellum; but in PC12 In chromocytoma cells, SMIM3 can be preferentially induced by NGF and EGF, and SMIM3 can also be strongly induced by forskolin, A23187 and ATP. [0003] The human SMIM3 gene is located at 5q33.1, and the cDNA of SMIM3 contains an open reading fr...
