CAPS is used commonly for Western Blot applications and other protein sorting procedures. In Towbin's transfer buffer, methanol increases the binding of small proteins to the membrane, SDS increases the mobility of large proteins. We Are trying to obtain efficient and reproducible western transfer of a 340 kDa protein. 1. I have some confusion about the amount of sample normally required to load on gel during Western blot. You can do dot-blots or ELISA based techniques instead of western if your protein conformation is that important. Methanol usually help in transferring small molecular weight of protein. 2. �� I used to do this. I'm going to perform a western blot analysis on cell lysate from human, adipose derived mesenchymal stem cells. When working with larger, high molecular weight proteins, elimination of the methanol results in a significant increase in protein transfer efficiency (For example, Thermo Scientific Co. produce 10X MeOH-free buffer for use with wet-tank transfer apparatus). pj�C�6s`%��ؠ���q���q�eʣ������N\���oZdZ`&���r�C̑"�jW���e��X� �w����͋���L�;�"4� © 2008-2020 ResearchGate GmbH. kindly help me. 2. The reason I wanted to avoid methanol in the transfer buffer is to know whether methanol can affect the protein conformation. h�bbd``b`W�c��$���E�l)�`�$X� �c b����b����G���A�Qa@�{)��d� SDS PAGE should be run at constant current or constant voltage?

Adding more methanol is reduce the solution's dielectric constant and increase the buffer's resistance and reduce it's conductivity. Tahnks. Without methanol or using lower concentration such as 10% transfer of protein will not perform optimally. Reduced. For me, fisrt, try nitrocellulose without methanol for transfert your native gels, Penn State Hershey Medical Center and Penn State College of Medicine. Also there are some protocols for blot buffers without methanol; but transfer will not perform optimally.
