Different Kinds Of Cancer ELISA Kits

By Lila Bryant


The enzyme linked immunosorbent assay or ELISA has been used as a tool in detecting the presence of a substance that is called an antigen in a wet or liquid sample. The cancer ELISA kits are used as a tool in recognizing any elements of any chemicals and responses from the immune system for any contagious microbes. The tests include an enzyme that is a result of a biochemical reaction. It includes an antigen molecules in the body.

Cancer Antigen 125 is a quickly quantify antigen concentrations in human serum. It has three features, it is easy, efficient and rapid. It is easy because it has features fixed in one system and no required additional equipment needed. It is efficient because the test can reach for 96 samples at once. It can give results in just less than 4 hours. The technology can allow you to screen any multiple serum samples for several antigens associated with cancers in a present and elevated levels.

The breast cancer susceptibility protein 1 is a great kit in specifying a breast tumor condition in a person. The strength of this tool is determined through a loss rate in an activity. It means that it only consist a five minute duration until it expires under a storing condition. To prevent a poor performance, the operating procedures, the lab conditions and the room temperature should be in good control.

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.

An early prostate cancer antigen 2 is usually composed of reagents and pre coated. It also consists of standard diluent, freeze dried or standard, wash buffer, stop solution, assay diluent A and B and detection reagent. The tool is made in different groups with different detection range, color developing time and sensitivity level.

The signal transduction assay reaction or the so called STAR is fast and a sensitive method of detecting a relative quantity of activated targets with the use of phospho antibodies. It is a solid phased enzyme that provides a scheme to detect a particular level of cell extract. The completion of the whole assay last for less than five 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.
