I am looking for a low MW protein to use as a std for gel filtration
chromatograpy. The lowest one I have found is aprotinin (6,500), I really
need one around 3,200 Da. I have tried the B-chain of insulin but it
elutes before aprotinin. I am currently using a 0.05M KPO4 (pH 3.72)
buffer. In the next couple of days I will probably increase the salt
content to see if that makes insulin behave any better. In the mean time
I welcome any suggestions that you may have.
Please respond by e-mail to mjlogan at whale.st.usm.edu
Thanks in advance
