Problems solved by technology

Existing SP10 protein test strips (David Sperm SP10 Protein Test Strip, Kim Xiuer Sperm SP10 Protein Test Reagent, FertilMARQ Fertility Sperm Test Kit, Spermcheck Fertility Home Test Kit, and BabystartFertilCount Male Fertility Test) are all based on colorimetric methods for identification. Only the qualitative identification of SP10 protein can be carried out, and the concentration of SP10 protein cannot be accurately quantified, which affects the accurate detection of sperm concentration; The price of a single root is about 40 yuan. Therefore, it can be seen that the prices of existing commercial products are generally high, which is not conducive to the promotion and use in poor areas.

Abstract

The invention provides a sperm SP10 protein detection test strip and a quantitative detection method, and belongs to the technical field of instant detection. According to the technical scheme, the detection test strip is arranged in a lateral flow mode, a substratum serves as a substrate, and a sample pad, a marking pad, a chromatography membrane and a water absorption pad are sequentially arranged on the substrate; a detection area and a quality control area are arranged on the chromatography membrane, and a functionalized nano material capable of being combined with SP10 protein is attached to the marking pad; and the two adjacent structures are partially overlapped. The test strip has the advantages that the test strip is used for quantitatively detecting the concentration of male sperms, a sample solution containing SP10 protein is directly dropwise added to the sample pad, quantitative detection of the concentration of the SP10 protein is achieved through signal collection and analysis of the detection area, and the test strip has the advantages of being easy and convenient to operate, low in cost, rapid in detection and the like; wide application prospects are realized in the field of male reproduction.

Description

technical field [0001] The invention relates to the technical field of instant detection, in particular to a sperm SP10 protein detection test strip and a quantitative detection method. Background technique [0002] According to the "Human Semen Examination and Processing Laboratory Manual", the main factors that cause male infertility include semen volume, total number of sperm, sperm concentration, normal sperm morphology, semen pH value and liquefaction time, etc. Among them, the sperm concentration is An important indicator to measure male infertility, when the concentration of sperm is less than 15×10 6 Individuals / mL, it is considered to be difficult to reproduce. Based on anatomical, genetic, and biochemical features, the SP10 protein, which has been shown to be useful as a biomarker of sperm concentration in men, is expressed only in the testis and is a marker of differentiation during the final step in spermatogenesis. According to the research, the concentration ...
