Cancer Antigen 72-4 (CA72-4) ELISA Kit

  • Created on the 11 May, 2017.

BACKGROUND

Cancer antigen 72-4 (CA72-4) was originally discovered as an antigenic determinant that is recognised by B 72.3 and it was named as TAG-72 (tumor associated antigen 72). TAG-72 protein has a molecular weight of 48 kDa. Elevated concentrations of CA 72-4 using either plasma or serum have been identified in a large number of malignant diseases such as carcinomas of stomach, pancreas, ovaries, cervix, colon and endometrium. There have also been several studies which have focused on the potential clinical usefulness of CA 72-4 in gynecological and gastrointestinal (GI) cancer, these have shown a sensitivity of approx. 50% in ovarian cancer and 40% in gastric and colorectal cancer, however, the overall specificity was greater than 95%. There is also a good correlation between the levels of CA 72-4 and tumor size and stage. CA 72-4 is now regarded as the primary marker of choice for therapeutic monitoring and the subsequent follow-up care of gastrointestinal cancer patients.

INTENDED USE

Human CA 72-4 ELISA kit is intended for measuring in vitro quantitative concentrations of cancer antigen 72-4 (tumor associated antigen 72, CA72-4, TAG-72) in human serum or plasma samples. This assay has a minimum sensitivity limit of 0.79 U/ml.

SENSITIVITY

The minimum detection sensitivity level of human CA 72-4 (TAG-72, tumor associated antigen 72) using this human cancer antigen 72-4 ELISA kit was 0.79 U/ml. The dynamic assay range for this kit is 3.0 – 100.0 U/ml.

I am a first time user and found that your instruction manual was very easy to follow. The insulin ELISA kit performed well and I was happy with the results that were generated.

I carried out a pilot study comparing the performance of many ELISA kits from different suppliers and found your kits to be one of the better performers. We observed good linearity and tight replicates.
