Time to Start Actin Like a Reliable 'Housekeeper'!

Fri, 05/18/2012 - 09:10

A growing body of data and studies using actin antibodies supports a view of the actin cytoskeleton of smooth muscle cells as a dynamic structure that plays an integral role in regulating the development of mechanical tension and the material properties of smooth muscle tissues. The increase in the proportion of filamentous actin that occurs in response to the stimulation of smooth muscle cells and the essential role of stimulus-induced actin polymerization and cytoskeletal dynamics has been convincingly documented using actin antibodies in many smooth muscle tissues and cells using a wide variety of experimental approaches including Western blotting(1).

Western Blot: Actin Antibody Western Blot: Actin Antibody

Western blotting is a powerful technique using antibodies to characterize a multitude of cellular proteins. As an internal control to assure even protein loading and gel migration, the blots are commonly probed with antibodies for ubiquitous "housekeeping" gene products. It has recently been shown that cell confluence significantly affects the levels of housekeeping genes; alpha-tubulin and Glyceraldehyde-3-Phosphate Dehydrogenase levels were affected by cell densities. On the other hand the levels of beta-actin remained unchanged at a wide range of cell densities, implying actin as a more reliable loading control (2).

Nice post. I was watching continuously this blog and I'm impressed! Extremely useful info specifically the last part I care for such info much. I was looking for this specific info for a long time. Thanks and best of luck.

I am so impressed I had to save it so I continously go back and read things I may have skimmed

Good post. I learn something new and challenging on websites
I stumbleupon everyday. It will always be exciting to read through
articles from other authors and practice a little something
from their sites.

I'm really impressed together with your writing skills as well as with the structure
on your weblog. Is that this a paid theme or did you modify
it your self? Either way stay up the excellent quality writing, it is rare to look a great blog like
this one today..
