Product name Human Carbohydrate antigen 50 (CA50) ELISA Kit
Reactivity Human
Applications ELISA
Applications notes This Human Carbohydrate antigen 50 (CA50) ELISA Kit employs a two-site sandwich ELISA to quantitate CA50 in samples. An antibody specific for CA50 has been pre-coated onto a microplate. Standards and samples are pipetted into the wells and anyCA50 present is bound by the immobilized antibody. After removing any unbound substances, a biotin-conjugated antibody specific for CA50 is added to the wells. After washing, Streptavidin conjugated Horseradish Peroxidase (HRP) is added to the wells. Following a wash to remove any unbound avidin-enzyme reagent, a substrate solution is added to the wells and color develops in proportion to the amount of CA50 bound in the initial step. The color development is stopped and the intensity of the color is measured.
Detection method Colorimetric
SampleType Cell culture supernatants, Other biological fluids, Plasma, Serum
Assay type Sandwich ELISA (quantitative)
Assay duration Multiple steps standard sandwich ELISA assay with a working time of 3-5 hours. It depends on the experience of the operation person.
Alternative CA50

Usage notes • Do not mix components from different kit lots or use reagents beyond the kit expiration date.
• Allow all reagents to warm to room temperature for at least 30 minutes before opening.
• Pre-rinse the pipet tip with reagent, use fresh pipet tips for each sample, standard and reagent to avoid contamination.
• Unused wells must be kept desiccated at 4 °C in the sealed bag provided.
• Mix Thoroughly is very important for the result. It is recommended using low frequency oscillator or slight hand shaking every 10 minutes.
• It is recommended that all samples and standards be assayed in duplicate or triplicate.
Storage instructions The unopened kit should be stored at 2 - 8°C. After opening, please store refer to protocols.
Shipping Gel pack with blue ice.

Additional Information

Background Carbohydrate antigen 50 (CA 50) is a tumor marker that increases in many malignancies, especially in carcinoma of the digestive tract. False-positive results occur in benign liver disease.Significant correlations with some liver tests were found, especially transaminases, and at lower degrees with cholestatic parameters. Despite the previously reported relation with cholestasis, especially in biliary diseases, the CA 50 serum levels of the authors' cirrhotic patients appeared to be more closely related to cytolysis, according to the results of several statistical tests, including multivariate analysis.Because of the percentage and the levels of the abnormal results, this antigen cannot be used as a tumor marker in cirrhotic patients. Cytolysis seems to have a pathogenetic role in the increase of CA 50, at least in cirrhosis.
