Citric acid assay kit SemenAssay®

for clinical chemistrytestosteronecalcium

The kit is used for quantitative detection of citric acid level presented in human seminal plasma specimens, while also used to determine the citric acid concentration in blood, body fluid, food and other types of specimens. Features: • With better accuracy of test resuit than the method recommended by WHO. The recovery rate of 0.2mmolL citric acid and of 1.6 mmoll citric acid is 102.3,100% respectively. • With good sensitivity and stability of the test results. Convenient to handle. • Opération in the microplate. Fast and easy-to-use. • Available for automatic and semiautomatic tests good for standardization of test. • It is ready for use and easy to handle. •40 tests per kit and meet the need of batch testing. The citric acid in the seminal plasma is secreted by prostate, which serves to form the complexation of calcium ion, adjust the calcium concentration in the seminal plasma, and affect the semen liquefaction process after ejaculation, as the lack of citric acid in the semen may cause the delay of seminal liquefaction. The level of citric acid in seminal plasma is bound up with the level of testosterone. The level of citric acid in seminal plasma is a key indicator serving to determine the secretion of androgens and evaluate the prostate functions. The decrease of citric acid level in seminal plasma is an evidence for the damage of prostate secretion function. Also, the citric acid plays an important role in the sperm motility and activity of hyaluronidase. 【Storage conditions and duration】 1. Storage conditions 1) The kit should be kept out of sun and stored at the temperature of 2-8° C.
