Sorry, the company was CloneTech, now it is Takara (not Takeda). You may talk with Dr. Gia Jokhadze, who is the director of protein chemistry department. He would give you more information. You can find his profile on linkedin. He is very nice person. Probably, you can ask some free sample from hi

Probably you can try His-Column from Clonetech (Takeda ?). They modified the column packing using nylon membrane, which offered better flow-through than that of traditional resin-gel column. On Wed, Feb 15, 2017 at 8:57 AM, Markus Seeliger wrote: > Dear all, > we are happy users of all that GE

We used cOmplete Histag column from Roche, 5 ml prepacked. We bought 3-4 prepacked columns and a bottle of 25 ml (cheaper). The nice thing about this Roche pack, if you closed the outlet and let the pump run into the inlet, the cap will slowly detach .. We use this trick to replace the resin in

I'll second those suggestions and also note that empty XK columns from GE regularly show up on eBay for pennies on the dollar. Roch cOmplete is really great in situations where there are chelators around (especially proteins secreted into eukaryotic tissue culture media). It saved me tremendous am

Well GE sells empty columns (XK for low back-pressure, tricorn for higher back-pressure) that you can fill with the resin you want. They seem expensive but for that kind of things I don't think any option will be real 'savings'. For nickel affinity we have been having good results with Roche's Comp

Hi Markus, BioRad has columns as well (prepacked and empty), which follow the establiched connector standard. So usable without the need of adapters. Cheers Christian Am 15.02.2017 um 16:57 schrieb Markus Seeliger: Dear all, we are happy users of all that GE offers around their FPLC system

Dear all, we are happy users of all that GE offers around their FPLC system, but I am getting a little tired of feeling monopolized. Are any of you aware of either empty columns or prepacked columns (e.g. metal affinity or ion exchange resins) from other companies? Thanks for your advice Markus
