Where can I order the MutS protein online?

Question

I don't know if anyone knows about this protein, but it binds to the mutations of DNA, and MutS can also be histidine-tagged. But I just want to know where I can get this protein, I tried a lot of sites like invitrogen, etc. but I haven't had any luck.

Answer 1

I doubt that you'll be able to find the purified protein commercially available.  All you need is an expression plasmid and a nickle column, and you can easily purify it yourself.  Check Pierce (http://www.piercenet.com/) for protein purification columns.

As for the plasmid, you can probably get it for free.  Read the following paper and contact the primary investigator (last author).  They have an expression plasmid for His-tagged MutS which you may find useful.

Best of luck.
