Dear All,
I want to do a UV-VIS analysis to measure the light absorbance of lignin. I'm wondering to ask that is there any protocol to prepare a lignin solution for this analysis? I would be more than happy to see your experience in this regard.

Thanks for your kind attention!
Instead of checking only the mRNA level, I want to check the active protein level of MMP-1 in Liver tissue from mice. How can I do that?
