 | Cancer antigen 15-3 (carbohydrate antigen 15-3, CA15-3) is an epitope located on the surface of MUC-1, a high molecular weight glycoprotein of the mucin family. CA15-3 is the most important specific marker of breast cancer, and the change of its amount is closely related to the treatment effect, which is the best indicator for diagnosing … Cancer Antigen 15-3 (CA15-3)">Continue reading Cancer Antigen 15-3 (CA15-3) | |
| Cancer antigen 242 (CA242) is a mucin with a sialylated carbohydrate structure, similar to the CA50 and CA19-9 antigenic determinants. CA242 is present in the mucosa of the pancreas and colorectal. The expression of CA242 in normal tissues is low. CA242 in serum can be used for auxiliary diagnosis and monitoring of treatment in patients … Cancer Antigen 242 (CA242)">Continue reading Cancer Antigen 242 (CA242) | |
| Cancer antigen 50 (CA50) is a carbohydrate antigen tumor marker, defined by the recognition site of monoclonal antibody C50. Its epitope structure includes sialic acid-N-tetraoxyceramide and sialylated Lewis blood group antigen, which is similar to the epitope structure of CA19-9 [1]. CA50 is used in the detection of a variety of malignant tumors such as … Cancer Antigen 50 (CA50)">Continue reading Cancer Antigen 50 (CA50) | |
| Carcinoembryonic antigen (CEA) exists on the surface of cancer cells differentiated from endoderm cells. Carcinoembryonic antigen is a broad-spectrum tumor marker, elevated in colorectal cancer, gastric cancer, lung cancer, pancreatic cancer, breast cancer, ovarian cancer, uterine and cervical cancer [1]. HKIG offers 2 monoclonal antibodies (catalog numbers: 1017101 and 1017201) for CEA detection. Anti CEA … Carcinoembryonic Antigen (CEA)">Continue reading Carcinoembryonic Antigen (CEA) | |
| Prostate Specific Antigen (PSA) is a single-chain glycoprotein secreted by prostate epithelial cells, which belongs to the kininase family, and exists in prostate tissue and semen. PSA can be present alone in free form (fPSA) or in a bound state (cPSA) by binding to α1-antichymotrypsin or α2-macroglobulin. The free form and bound form of PSA … Free Prostate-Specific Antigen (fPSA)">Continue reading Free Prostate-Specific Antigen (fPSA) | |
| Human epididymal protein 4 (HE4) was first discovered in human distal epididymal epithelial cells. Human epididymal protein 4 and CA125 levels have a strong correlation in the diagnosis and treatment of ovarian cancer patients, and serum HE4 levels can be used as tumor markers to evaluate the efficacy of ovarian cancer treatment [1]. HKIG currently … Human Epididymal Protein 4 (HE4)">Continue reading Human Epididymal Protein 4 (HE4) |
