Ovarian antibodies (to ovarian cell antigens) were first identified in women with premature menopause, infertility, and in vitro fertilization. This group of antibodies may include antibodies to Leydig cells, ovarian granulosa cells, and placental syncytiotrophoblasts.
Osteocalcin is a vitamin K-dependent non-collagenous protein of bone tissue (vitamin K is necessary for the synthesis of active protein centers that bind calcium) - it is localized mainly in the extracellular matrix of bone and makes up 25% of the non-collagenous matrix.
The sensitivity of the ELISA method for diagnostics of opisthorchiasis in the acute phase approaches 100%, in the chronic phase of the disease - 70%, depending on the intensity of the invasion. IgM antibodies appear in the blood 1 week after infection, reach maximum values 1.5-2 weeks later, and after 6-8 weeks their titer begins to decrease rapidly.
Markers of malignant growth include substances of different nature: antigens, hormones, enzymes, glycoproteins, lipids, proteins, metabolites. The synthesis of markers is determined by the peculiarities of the metabolism of the cancer cell.
CA 242 is a glycoprotein that is expressed on the same mucin apoprotein as CA 19-9. In benign tumors, CA 242 expression is low, while in malignant tumors its expression is significantly higher compared to CA 19-9.
