What is a protein marker? The classification of protein marker.

In The Western Blot process, the molecular weight Marker is like a screw, not a small detail, but such a small detail has a role to play in the results of the experiment. The role of this Western Blot reference family is mainly used to indicate the molecular weight of the protein strip corresponding to the size, only the standard amount is accurate, the experimental results are persuasive, in addition, the protein standard also indicates the transfer success or the degree of electrophoresis of the protein on the gel and so on, so the selection of the correct protein Marker is also one of the necessary conditions for the success of the Western blot experiment.

Overall, protein molecular weight standards can be divided into two levels of un dyed protein molecular weight standard, pre-dyed protein molecular weight standard. Here's a little description of the protein molecular weight standard:
