Poly(N-isopropylacrylamide) (PNiPAM)

CAS Number:
25189-55-3
Grouped product items
Catalog Number Unit Size QTY
21458-1 1 g
21458-10 10 g

Product Overview

Polymer is water-soluble at room temperature, insoluble above ~40º. Solubility ceiling has been used in mold and cell growth techniques since cells adhere to polymer film at incubation temperatures and are released as medium is cooled and polymer is dissolved.

Synonyms: PNIPAM; Poly(N-isopropylacrylamide); PolyNIPAAm; NIPAM polymer
Shipping Requirements:
None
