[0028] The third step is to measure the background value of anti-Müllerian hormone and store it temporarily at 2-8°C;
[0029] In the fourth step, according to the background value determined in the third step, anti-Müllerian hormone-positive substances are added, and the concentrations are 1.0ng / ml, 5.0ng / ml, and 15.0ng / ml respectively;
[0030] The fifth step is to store the substance obtained in the fourth step at a temperature of 2-8°C for 3-14 days, so that the com...

[0032] 1. Stability
[0033] Three-level (1.0ng / ml, 5.0ng / ml, 15.0ng / ml) quality control products were tested in turn by storing them at 2-8°C after reconstitution, accelerating at 37°C in a freeze-dried state, and testing the number of freeze-thaw cycles after reconstitution. The test data are shown in Table 1 below:
[0034] Table 1
[0035]
[0036] From the data in the table, it can be seen that the anti-Müllerian hormone quality control product was opened and reconstituted, stored at 2-8°C for 14 days, heat-accelerated at 37°C for 14 days, and after repeated freezing and thawing for 5 times, the decrease was less than 5%. The stability meets the requirements.
[0037] 2. Check the consistency between platforms
[0038] Three-level (1.0ng / ml, 5.0ng / ml, 15.0ng / ml) quality control substances were tested on mainstream platforms (Roche, Beckman) respectively. The te...

Abstract
The invention discloses a preparation method of an anti-Mullerian hormonequality control substance. The preparation method comprises the following steps: selecting hormone removing blood serum meeting the demand; adding Proclin300, gentamicinsulfate, sodiumazide, thiomersalate and trehalose to be uniformly mixed; first, measuring a background value of the anti-Mullerian hormone; then adding ananti-Mullerian hormone positive substance to the set value 0.5-20.0 ng / mL; and sub-packaging the substance obtained in the S4 in a specification of 1.0 ml / bottle in a 4 ml brown glass bottle for vacuum freezing and drying to obtain the anti-Mullerian hormone quality control substance and storing the anti-Mullerian hormone quality control substance at 2-8 DEG C. The quality control substance selects the hormone removing blood serum and can be in commercial production. Meanwhile, as the anti-Mullerian hormone quality control substance is high in consistence to a normal human sample, the matrix effect is reduced to the maximum extent, so that the anti-Mullerian hormone quality control substance is suitable for instruments and reagents of mainstream factories. The quality control substance isa freeze-dried quality control substance which is high in stability, is not affected by factors such as transportation and temperature, and is stable in performance.
Description
technical field [0001] The invention relates to biological products, in particular to a preparation method of an anti-Müllerian hormone quality control product. Background technique [0002] Serum anti-Mullerian hormone (Anti-Mullerian Hormone, AMH) is a dimeric glycoprotein secreted by female follicular granulosa cells and male testicular Sertoli cells, which can inhibit the recruitment and growth of female follicles and regulate the function of male testicular Leydig cells . Most of the articles published so far describe its clinical application. For example, detecting serum AMH levels can be used to evaluate ovarian reserve, predict ovarian response in assisted reproduction, evaluate ovarian reserve in tumor patients, and assist in the diagnosis of polycystic ovary syndrome, ovarian cancer, and ovarian cancer. Premature aging and predicting menopause, etc. [0003] The level of AMH is not affected by pituitary gonadotropins, and the value changes little throughout the m...
