Spinach Trx(Thioredoxin) ELISA Kit

Spinach Trx(Thioredoxin) ELISA Kit is a research-use ELISA kit from ELK Biotechnology for measuring Spinach Trx in Plant tissue or cell culture supernates samples from Spinach. Use the listed assay range, sample guidance and protocol documents to assess suitability for the intended study.

Test principle

The test principle applied in this kit is Sandwich enzyme immunoassay. The microtiter plate provided in this kit has been pre-coated with an antibody specific to Spinach Trx. Standards or samples are added to the appropriate microtiter plate wells then with a biotin-conjugated antibody specific to Spinach Trx. Next, Avidin conjugated to Horseradish Peroxidase (HRP) is added to each microplate well and incubated. After TMB substrate solution is added, only those wells that contain Spinach Trx, biotin-conjugated antibody and enzyme-conjugated Avidin will exhibit a change in color. The enzyme-substrate reaction is terminated by the addition of sulphuric acid solution and the color change is measured spectrophotometrically at a wavelength of 450nm ± 10nm. The concentration of Spinach Trx in the samples is then determined by comparing the OD of the samples to the standard curve.
