What if your mild urea condition unfolds your protein from a globular to a stretched elongated form ? You probably have done CD already to verify that this is not the case. Jürgen .. Jürgen Bosch Johns Hopkins Bloomberg School of Public Health Department of Biochemistry & Mol

Dear Careina, Could you tell what reason you have to believe that your protein is oligomerising? If your protein is forming oligomers, you should be able to detect them using crosslinking or Native PAGE. Do you have access to an analytical ultracentrifuge? cheers Ganesh Le 14/11/12 08

2012-11-13 Thread Careina Edgooms
Anyone have any advice on how to detect whether my protein is forming oligomers? It is monomeric in the native state but I have reason to believe that it may be oligomerising in mild concentrations of urea (intermediate state). I have tried cross linking and BN PAGE and they are inconclusive. SE
