Likewise, is Western blot quantitative?
Western blot is a reliable quantitative method only if sample properties and integrity, antibody specificity to the target protein, and loading protocols are considered. With careful attention to details, you can avoid common mistakes and avoid misinterpreting Western blot data.
Secondly, why is it called Western blot? The name western blot is a play on the Southern blot, a technique for DNA detection named after its inventor, English biologist Edwin Southern. Similarly, detection of RNA is termed as northern blot.
Beside this, what is a Western Blot used for?
A western blot is a laboratory method used to detect specific protein molecules from among a mixture of proteins. Next, the protein molecules are separated according to their sizes using a method called gel electrophoresis. Following separation, the proteins are transferred from the gel onto a blotting membrane.
What is densitometry Western blot?
Densitometry data generated for Western blots are commonly used to compare protein abundance between samples. Nonlinear densitometry data were observed when Western blots were detected using infrared fluorescence or chemiluminescence, and under different SDS-PAGE conditions.
