详细说明

MP Biomedicals - 02150097

Potassium Salt
Far superior fluorescent probe used in protein studies. This is a dimer of ANS, with a dissociation constant two orders of magnitude smaller than ANS, making it extremely sensitive.

Sigma Aldrich - D4162

Application
Bifunctional fluorescent probe for proteins.

Sigma Aldrich - 49058

Other Notes
Potent inhibitor of in vitro microtubule assembly used to investigate structural changes in tubulin monomers & dimers1,2; particularly high affinity for nucleotide binding sites of some proteins3

Toronto Research Chemicals - D416480

4,4'-Dianilino-1,1'-binaphthyl-5,5'-disulfonic Acid is a bifunctional fluorescent probe for proteins.
