HE4 antigen is a glycoprotein with a molecular weight of about 20-25 KD. HE4 antigen is a tumor marker of ovarian cancer.In ovarian cancer cases, HE4 is considered as one of the early warning factors, which can indicate the degree of risk of cancer and is

SCC antigen is a glycoprotein with a molecular weight of about 48 KD. SCC antigen is a tumor marker for cervical, vaginal, lung, brain and esophageal cancer. In cervical cancer cases, SCC is used as one of the early predictors, which can indicate the risk

Neuron-specific enolase (NSE) is a tumor marker currently used to detect small cell lung cancer (SCLC). SCLC is sensitive to combined chemotherapy and radiotherapy, and serum NSE concentration will mostly decrease to normal level in the treatment.But most

Tumor-associated antigen 72-4 (CA72-4) is a tumor-associated glycoprotein antigen recognized by IgG-type monoclonal antibody B72.3, called TAG-72 (Tumor Associated Glycoprotein 72), which immunizes mice with cancer cell membrane components of human breast

CA242 is a sialylated carbohydrate antigen that can be recognized by CA242 monoclonal antibody.It is a mucin-type glycoprotein that is low in the serum of healthy people and patients with benign diseases. When malignant tumors occur in the digestive tract

Cytokeratins are structural proteins of epithelial cells.So far, 20 different cytokeratins have been found.Due to their special distribution form, cytokeratin has now become a dividing indicator in the study of tumor pathology.Complete cytokeratin polypep

CA15-3 is a glycoprotein with a molecular weight of 400 KD. The detection of blood CA15-3 is mainly used for the monitoring and screening of breast cancer. CA15-3 is a useful tumor marker to evalsuate the prognosis of patients.CA15-3 is generally considere

Carcinoembryonic Antigen (CEA) is composed of a number of glycoproteins with molecular weights of 175-200 KD, which vary depending on the amount of sugars and amino acids contained.Although the biological function of CEA is not well defined, it is still t

AFP is a polypeptide chain glycoprotein with a molecule of 70KD, consisting of 590 amino acid residues, containing 4%.The sugar chain is N-glycan on the asparagine at position 232.Oligosaccharides consisting mainly of mannose, galactose, N-acetylglucose a

The carbohydrate antigen CA19-9 is a mucin-type carbohydrate tumor marker with a molecular weight of 10 kDa.This mucin can be expressed on the cell membranes of pancreas, gastrointestinal mucosa and liver tissue in normal fetuses and adults, and can be re

CA50 is a carbohydrate antigen mainly composed of sialic acid glycolipids and sialoglycoproteins, which is elevated in body fluids and tissues of patients with multiple epithelial malignancies.The kit is used for auxiliary diagnosis, efficacy evalsuation a

Free prostate-specific antigen (F-PSA) is a single-chain glycoprotein with a molecular weight of 34000 secreted by prostate epithelial cells and is a serine proteolytic enzyme.About 80% of serum free prostate-specific antigen (F-PSA) binds to some proteas

Total prostate-specific antigen (t-PSA), a 32KD single-chain glycoprotein secreted by prostate epithelial cells, is a chymotrypsin-like serine protease.Under normal conditions, PSA secretes into semen and plays a physiological role in the division of semi

CA125, a tumor-associated glycoprotein tumor marker with a molecular weight of 200-1000 kDa, is expressed on the membrane of cancerous ovarian epithelial cells and can be released into the cell interstitium and patient serum.
