Hi,
trick is to figure out the chemical company that really synthesizes the
product as many parties buy the stuff from one supplier only and repack
it into smaller bottles and reprice it (at considerably higher costs).
In the Sigma catalogue for example, these products were once marked with
the shor-hand "pfs" (prepared for Sigma).
Here is a link to a company that will synthesize it for a nice price:
https://www.applichem.com/shop/produktdetail/as/chaps-ibiochemicai/
Negociate with them and you will probable get it cheaper....
Alternative, synthezise it yourself (see publications on applichem page)....
Good luck,
Jeroen

Hi Sebastiano,
we often buy chemicals (including CHAPS) from Melford:
https://www.melford.co.uk/products/biochemicals/detergents-surfactants/chaps-1-g.html
It is often cheaper than Sigma-Aldrich.
Hope that helps,
Tomas

Dear all,
we are considering whether to buy the columns and reagents to purify our own
Wnt3 protein or to buy it.
Given that the purification requires large amount of column eluents with 1%
CHAPS, we are looking for the cheapest CHAPS provider to understand if the
in-house purification is worth the cost.
Could anybody share their experience with low-cost chemical providers, please?
Thank you very much,
have a nice weekend,
Sebastiano
