The same procedure can be used to quantify DNA or RNA bands on agaros.
WESTERN BLOT QUANTIFICATION USING IMAGEJ HOW TO
Thus, inhibiting USP11-mediated tau deubiquitination may provide an effective therapeutic opportunity to protect women from increased vulnerability to AD and other tauopathies. For a quick introduction to the layout of the ImageJ program, see here. This video shows you how to quantify bands on an image of an SDS-PAGE gel using ImageJ. This approach utilizes a two-step procedure where each lane of a blot is identified in the image, and then individual bands are identified inside each lane. The other common approach for quantitating western blots is commonly referred to as using lane and band tools. USP11 levels also strongly associate positively with tau pathology in females but not males. Western Blot Image Analysis: Lane and Band Tools. Genetic elimination of usp11 in a tauopathy mouse model preferentially protects females from acetylated tau accumulation, tau pathology, and cognitive impairment. USP11 escapes complete X-inactivation, and female mice and people both exhibit higher USP11 levels than males. Removal of ubiquitin provides access for enzymatic tau acetylation at lysines 281 and 274. Here, we demonstrate through in vitro and in vivo models, as well as human AD brain tissue, that X-linked ubiquitin specific peptidase 11 (USP11) augments pathological tau aggregation via tau deubiquitination initiated at lysine-281. Band intensity was calculated using ImageJ software. 2A).All images were analyzed with both methodologies, densitometer and ImageJ. (B) The efficiency of SIRT2 knockdown was verified by Western blot.
Although women experience significantly higher tau burden and increased risk for Alzheimer’s disease (AD) than men, the underlying mechanism for this vulnerability has not been explained. In a first attempt, we compared the image band quantification with a densitometer and by ImageJ analysis, using previous Western blot results in which different background levels, even non-uniform background, were observed (Fig.
