Biological Activity

[Description]:

Bis-ANS dipotassium is a fluorescent probe of hydrophobic protein. Bis-ANS binds to tubulin with a Kd of 2 μM[1]. Bis-ANS dipotassium is a potent biphasic modulator of protein liquid-liquid phase separation (LLPS). Bis-ANS dipotassium promotes LLPS at low concentrations but suppresses LLPS at high concentrations[2].

[In Vitro]

Bis-ANS is a fluorescent molecule that has been used to probe exposed hydrophobic patches in proteins and to monitor the formation of protein aggregates. Bis-ANS is a bivalent naphthalene sulfonate with aniline moieties. Bis-ANS modulates the liquid-liquid phase separation of TDP-43 low complexity domain (LCD)[2].
