Potassium acetate 3 M, pH 5.5
3 M potassium-acetate concentrate at pH 5.5 — alkaline-lysis neutralisation for plasmid-DNA (pDNA) processing. · GMP catalogue product · CT-76500
Potassium acetate 3 M, pH 5.5 is a defined concentrate for plasmid-DNA processing. It neutralises the alkaline-lysis step in pDNA purification, precipitating SDS and cell debris while the plasmid stays in solution.
Why
- Alkaline-lysis neutralisation — neutralises the lysis step in pDNA prep.
- pDNA processing — precipitates SDS, protein and debris.
- GMP grade — for regulated processing.
- Multi-application — cell & gene therapy and mRNA (template).
