Product category: Diagnostic tests for cancer
ELISA kits – № 100-21 OnkoEIA-CA 125
CA 125 is an oncofetal protein. It is a mucoglycoprotein with a molecular weight of over 200 000 Da. Normally in adults CA 125 exists in two forms: free and membrane-bound. Membrane-bound antigen can be identified on the surface of epithelial cells of fallopian tubes, cervix, endometrion, bronchi, mammary gland and sudoriferous gland. High concentrations of free form can be detected in seminal liquid, breast milk, vaginal secretions, saliva, bronchoalveolar and intraperitoneal liquids. In bloodstream CA 125 persists in low concentrations. Increased concentration of serum CA 125 is a sign of ovarian pathology (either benign or malignant).

Quantitative determination of serum CA 125 is used for monitoring of patients with ovarian cancer for estimation of treatment efficiency, early identification of recurrences and asymptomatic dissemination of residual tumor. Diagnostic value of method depends on histological type of tumor: it is the highest in the case of serous ovarian carcinomas in comparison with other types of carcinoma (e.g. mucinous carcinoma).

OncoEIA-CA 125 kit is intended for the quantitative determination of cancer antigen CA 125 in human serum.

ELISA kits – № 100-17 OnkoEIA-total PSA
Prostate-specific antigen (PSA) is a single-chain glycoprotein with a molecular weight of about 32 000 Da. It is a serine protease that is produced only by human prostate epithelium. Normally PSA is secreted into seminal fluid in high concentrations. There it exhibits its enzymatic activity and is directly involved into liquefaction of seminal clot. In serum PSA persists in low concentrations. Increase of PSA concentration in serum is a sign of prostate pathologies, such as benign hyperplasia or malignant degeneration of prostate tissues. PSA determination is widely used for the revealing and monitoring of prostate cancer patients.

It was demonstrated that PSA makes stabile complexes with different protease inhibitors. The main part of the serum PSA is a complex with α1-antichymothrypsine (PSA-ACT). But there is a great difference in free PSA/PSA-ACT ratio in different groups of patients. In the case of benign hyperplasia the part of free PSA is higher than in the case of prostate cancer.

OnkoEIA-total PSA kit is intended for the quantitative determination of prostate-specific antigen in human serum.

Product category: Diagnostic tests for cancer
ELISA kits – № 100-18 OnkoEIA-free PSA
Prostate-specific antigen (PSA) is a glycoprotein with a molecular weight of about 32 000 Da, that consists of one polypeptide chain.

In the serum the PSA contains in two forms. It is the free form and connected with various fibers of blood.The main part of the serum PSA is a complex with α1-antichymothrypsine (PSA-ACT). But there is a great difference in free PSA/PSA-ACT ratio in different groups of patients. In the case of benign hyperplasia the part of free PSA is higher than in the case of prostate cancer.

OnkoEIA-free PSA kit is intended for the quantitative determination of free fraction of the prostate-specific antigen in human serum.
