Hello,
I am facing problem in visualizing protein of 10 KDa size on 15 % SDS PAGE gel. What are the suggestions for solving this problem?
Thanks,

Betr try wid 20% SDS PAGE gel.Kindly check wid d link provided.

Hi Patil,
15% gel is well and good for 10kd protein. You can try out 20% gel as well.
However, to get better run on 15% of the gel you can follow some tips!
1. Run the gel at lower voltage (70V) for longer time.
2. Freshly prepare the gel just before you load your samples. This is slightly advantageous over precast gels.
3. Load higher amount (50mg) of protein. So that you can get better band for 10kd protein.
-- Best regards.
For small proteins up to 20 kDa tricine-gels will work better than tris-glycine. In addition, gradient gels (say, 8-18%) will lead to narrower bands. See doi:10.1038/nprot.2006.4, doi:10.1016/0003-2697(87)90587-2
I have found that a specific treatment influences the Ct value of both the reference gene (Actin and Ubiquitin) in RT qPCR experiment. Is it possible to analyze such data?
