The kit is used for quantitative detection of anti-thyroid peroxidase antibody (TPO-Ab) in human serum in vitro.The detection of thyroid peroxidase antibody in human serum by this kit is of great significance for Hashimoto's thyroiditis, thyrotoxicos

Dehydroisoandrosterone (DHA) in maternal and fetal blood after pregnancy is converted into E2 and E140:60 in placental tissue.Estradiol (E2), a steroid hormone, is released into the blood mainly by ovary, placenta or testis secretion. E2 is the most biolo

Follicle stimulating hormone (FSH) is a glycoprotein hormone with a molecular weight of 30,000, secreted by the anterior pituitary gland.There are alpha and beta chains, whose main physiological function is to act on the gonads, to promote folliculogenesi

Luteinizing Hormone (LH) is a glycoprotein hormone secreted by the anterior pituitary gland with a molecular weight of 26,000 and consists of alpha and beta subunits. Its main physiological function is to promote follicular maturation and estrogen synthes

Prolactin (PRL) is a polypeptide with a molecular weight of 22,000 secreted by the anterior pituitary gland and consists of 198 amino acid residues. Its structure is similar to that of hGH. PRL secretion is regulated by prolactin release stimulation (PRH)

 The true progesterone in human body is progesterone. The corpus luteum of women with normal menstrual cycle is the main source of progesterone. The progesterone production rate is about 23mg/24h before ovulation. After ovulation, the corpus luteum is form

Testosterone and follicle-stimulating hormone together promote sperm formation and maturation, and are associated with sperm motility and sperm tube metabolism, and testosterone stimulates each stage of sperm meiosis.Testosterone can promote protein synth

Human chorionic gonadotrophin (HCG) is a glycoprotein hormone with a molecular weight of 36700 secreted by human placental trophoblast cells.The 37 amino acids in the protein part constitute two subunits, alpha subunit is the same as FSH, LH and TSH, only 

 HBcAb is an immunoglobulin produced by hepatocytes stimulated by viruses. The presence of HBcAb positivity indicates that hepatitis B virus replication is active in the liver, hepatocytes are damaged and infectious.

 Anti-hepatitis B e antibody (Anti-HBe) appears after the hepatitis B e antigen has turned negative. Anti-HBe positive indicates that the infectivity of patients has been relatively reduced, and the degree of virus replication has been reduced or alleviate

 Hepatitis B virus e antigen (HBeAg) appears simultaneously with or after hepatitis B surface antigen (HBsAg) after hepatitis B virus infection, and the peak of HBsAg in blood is also the peak of HBeAg.Positive HBeAg indicates active replication and strong

The kit is used for quantitative detection of hepatitis B virus surface antibody in human serum or plasma in vitro. Hepatitis B virus surface antibodies (Anti-HBs) generally appear after the body is infected with HBV or vaccinated with hepatitis B vaccin

The kit is used for quantitative determination of hepatitis B virus surface antigen (HBsAg) in human serum or plasma in vitro. Hepatitis B virus surface antigen (HBsAg), the outer membrane protein of hepatitis B virus, is the first HBV marker in serum.

C-peptide is a connecting peptide between the alpha and beta chains of proinsulin and consists of 31 amino acids with a molecular weight of 3021.In islet beta cells, the single-chain polypeptide proinsulin membrane-dependent protease cleaves into equimola

Ferrtin Fer is a glycoprotein with a molecular weight of 450,000, which is high in liver, spleen and bone marrow.Each ferritin molecule can store 4500 iron atoms.Ferritin is also involved in cell metabolism, cell proliferation and immune regulation.Ferrit

 The determination of islet (Ins) antibody can guide the dosage of insulin and the choice of insulin dosage form in type I diabetic patients. In addition, it can explain the reason of the low insulin release curve, that is, the decline of islet function or
