Different Kinds Of Cancer ELISA Kits

By Lila Bryant


First of all, it is important to know the meaning of ELISA. This is an abbreviation for enzyme linked immunosorbent assay. The Cancer ELISA kits are used for the components of the chemicals and immune system in detecting the responses in the body for any infectious microbes. The test involves an enzyme or a protein that causes a certain reaction. It involves any antigen the body.

The cancer antigen 125 is quick kit to identify an antigen concentration in the human serum. It usually comes with three characteristics. It is usually easy, rapid and efficient. It is easy due to its characteristics that can be found in one scheme only that needs no other equipment to function. It is efficient due to the test that can reach up to 96 samples and can give a result within four hours. This is the best tool to screen a serum sample for many antigens that detects cancers.

Another is the breast cancer susceptibility protein 1 or the BRCA1. This is a high sensitive kit to specify and detect anyone who has breast tumor. This kit is identified by a loss of rate in activity. This loss rate is less than five percent in the duration of the expiry date under a necessary storage condition. To have a lesser impact on the performance, the laboratory state and operating procedures, such as room temperature must be controlled.

Tumor marker for lung cancer. This is a sandwich type of kit with quantitative measurement of the tumor, other biological serum and in the plasma. This composed of perfect specificity that detects an antigen. It has a lower limit of detection that was contain the lowest concentration of protein that could be recognized from zero.

The early prostate cancer antigen 2 is composed of reagents, plate sealer, pre coated, 96 well strip plate, detection reagent and standard diluent. It is also composed of wash buffer and stop solution. These came by batches with different detection, sensitivity and developing capabilities.

The signal transduction assay reaction is a sensitive and fast method to detect a comparable amount of activated targets in using a Phospho specific antibodies. This is a sandwich enzyme which provides a system in detecting a specific signaling target in a cell passage. The process may take less than 5 hours.

Another is the ovarian cancer marker. The kit applies a competitive enzyme immunoassay technique that used a monoclonal antibody. The sample and the buffer are developed together within one hour. Once the incubation procedure was done, the wells are drained and washed for about five repetitions.

A DNA damage EIA is also a competitive colorimetric enzyme immunoassay that may last for 2.5 hours. It has already proven that samples are convenient and supplied with a 96 well plate format. The assessment of DNA are through urine, saliva and serum. The samples are composed of plasma, seminal fluids, culture supernatant, DNA extracts and cell lysates.

These kits serve as a great instrument to determine if a person or animal has already tumors in their body parts. This is useful for most physicians, since it is fast and reliable tests. This is only for diagnostic purposes and to identify if tumors are already formed in the body.
