General description

IGEPAL® CA-630 is a nonionic, non-denaturing detergent suitable for solubilization, isolation and purification of membrane protein complexes.It is chemically indistinguishable from Nonidet P-40.


IGEPAL® CA-630 has been used
  • as neutral detergent in homogenizing buffer during western blotting of mouse muscle homogenates
  • In X-gal staining for studying the lacZ expression in E8.5-E10.5 embryos
  • In Cell-Lysis (CL) buffer for preparing RT-qPCR-ready cell lysates


50, 100 mL in glass bottle

Other Notes

Nonionic, non-denaturing detergent


Chemically indistinguishable from Nonidet P-40, which is no longer commercially available.


May develop turbidity or sediment during storage. A clear liquid can be obtained on heating to 40°C.

Sample nucleic acid purification can often be rate-limiting for conventional quantitative PCR (qPCR) workflows. We recently developed high-throughput virus microneutralization assays using an endpoint assessment approach based on reverse transcription qPCR (RT-qPCR).
