Human Cytokeratin 2e ELISA Kit

Description

Human Cytokeratin 2e ELISA Kit is a 90 minute sandwich Enzyme-Linked Immunosorbent Assay (sELISA) designed for the in vitro quantitative determination of human Cytokeratin 2e in serum, plasma, and other biological fluids.

Assay Type

Sandwich (quantitative)

Principle of Assay

Human Cytokeratin 2e ELISA Kit (A312193) employs the sandwich enzyme immunoassay technique for the quantitative measurement of human Cytokeratin 2e in serum, plasma or other biological fluids. An antibody specific for Cytokeratin 2e has been pre-coated onto a 96-well microtiter plate. The standards and test samples are added into the wells and the Cytokeratin 2e present in each sample is bound to the wells by the immobilized antibody. Biotinylated Anti-Cytokeratin 2e Antibody, which also binds the Cytokeratin 2e present in each sample, and Streptavidin-HRP, which binds the Biotinylated Anti-Cytokeratin 2e Antibody, are added and the microtiter plate is incubated. Following incubation, unbound Biotinylated Anti-Cytokeratin 2e Antibody and unbound Streptavidin-HRP are removed by washing, and two substrate solutions are added to the wells. Color develops in proportion to the amount of Cytokeratin 2e captured in each well. The color development is stopped by addition of stop solution which changes the color from blue to yellow and the intensity of the color is then measured. The concentration of Cytokeratin 2e in the samples can then be calculated by reading the O.D. absorbance at 450nm in a microplate reader and referring to the standard curve.

Required Materials

The following materials are not included in the kit, but are required to run this assay:

Microplate reader capable of measuring absorbance at 450nm ± 10nm.
Squirt bottle, multichannel pipette reservoir, or automated microplate washer.
Graph paper or computer software capable of generating logarithmic functions.
Test tubes and Eppendorf tubes to prepare standards and samples.
Multi- and single-channel pipettes and sterile pipette tips.
Deionized or distilled water.
Absorbent paper towels.
37°C incubator.

Important Notes

Samples cannot be diluted for use with this kit. Owing to the material used to prepare the kit, sample matrix interference may falsely depress the specificity and accuracy of the assay.
Sample concentrations should be estimated before being used in the assay. If the sample concentration is not within the range of the standard curve, users must contact us to determine the optimal sample for their experiments.
Samples containing Sodium Azide (NaN₃) cannot be used in this assay. NaN₃ inhibits the activity of Horseradish Peroxidase (HRP) which is used in the detection step.
This ELISA kit is intended for the analysis of biological samples and has not been validated for purified/recombinant proteins, industrial, or commercial materials. Performance with such samples cannot be guaranteed, as differences in expression, sequence, tags, folding, post-translational modifications, purity, activity, or buffer composition may affect assay results.
