Tubulin

The use of Beta Actin (AC-15) as a loading control across multiple species

Actin is a fundamental component of the cytoskeleton, where it has the ability to create and break down actin filament formation in response to various cell needs.  Actin has six highly conserved isoforms, however beta and gamma actin are the two isoforms that are highly and ubiquitously expressed in the cell.  For this reason, measuring beta-actin levels has served as a useful control in research experiments in order to have a baseline of protein expression to compare cell manipulations to.  However, beta actin has other implications in scientific research aside from acting

The use of actin as a loading control in research on fruiting-body development and vegetative growth in Sordaria macrospora research

Sordaria macrospora is a filamentous fungus that serves as very useful system for scientific research due to a short life cycle and easy manipulation.  Just like any other model organism, it is important to have an effective loading control to validate experiments in the Sordaria macrospora.  In addition, the growth and morphogenesis of filamentous fungi is dependent on actin organization.  Actin is a very abundant protein across biological species and can transition between monomeric and filamentous states.  Actin has an alpha and beta isoform, both of which sha

The GAPDH Antibody in Western blot Assays

The loading controls on our antibody database are widely used in gel electrophoresis and Western blotting studies. Products like the GAPDH antibody detect "housekeeping" proteins which are abundantly distributed in cells. This makes them useful for checking the even loading of gel samples, and the even transfer of proteins at the blotting stage. They also serve a purpose in quality control, by verifying reagents are working correctly, and in the standardization of experimental results.

Who Needs Antibodies for Tubulin Modifications?

Tubulin is a heterodimeric complex composed of alpha and beta subunits. Just like histones, tubulin can undergo post-translational modification, to affect cellular function. Novus Biologicals offers a large database of modified Tubulin antibody products.
