What are sources of inconsistencies in western blot …
WebDec 18, 2015 · Blots imaged at different stages in the reaction, due to delays such as waiting for the darkroom, will be inconsistent. Even identical blots imaged at the same time can produce inconsistent results (see Fig. 1). Accuracy is further compromised by stripping and re-probing chemiluminescent blots to detect multiple targets. WebFeb 8, 2024 · Remove Background noise: You must have observed a major problem in western blot analysis is the high background noise, such as one side of the blot being darker than the other side. It causes inconsistencies in your results. The issue can be solved using some software packages that calculate the background around the target protein. … inclusion\\u0027s 77

WebFeb 2, 2024 · The results of ELISA and TPPA were inconsistent in 163 serum samples, accounting for 4.1% (163/3 972) of the total retest samples. Of 163 samples, 29 were ELISA − /TPPA + or ELISA − /TPPA reserved, accounting for 17.8% (29/163); and 134 were ELISA + /TPPA − or ELISA + /TPPA reserved, accounting for 82.2% (134/163). WebSep 27, 2024 · While the problems just discussed are some of the most prevalent, they are far from being the only issues encountered when running western blots. Smeared lanes, ‘smiling’ bands, and inconsistent data between experiments are other frequent complaints, along with issues that are unique to different detection methods. inclusion\\u0027s 74
