HTRF - Alpha-tubulin housekeeping - 500 tests 1 Kit

Alternative ELISA et WB, plus simple, plus rapide, très sensible, facilement miniaturisable / automatisable et peu onéreuse.

This assay is designed to measure the endogenous expression level of alpha-tubulin in cells and tissues in order to normalize data obtained on the phospho- and/or total protein(s) of interest. Due to its essential role in the cytoskeletons of cells, alpha-tubulin is ubiquitously and constitutively expressed in every tissue. Moreover, its amino acid sequence is highly conserved and is thus identical in almost all species. These characteristics make it one of the most commonly used housekeeping proteins. Its concentration is proportional to cell numbers and total protein concentrations, and it is therefore used as an internal control for data normalization to correct for signal changes caused by experimental variability (e.g. number of cells remaining in the culture plate after treatment, or lysis efficacy). The low sample volume of 4 µL and its compatibility with all Cisbios lysis buffers enable a multi-parametric analysis with the detection of alpha-tubulin in parallel with the phospho- and/or total protein(s) on the same lysate.
