Basic Information

Product Description

Product Name：Proteinase K

CAS No: 39450-01-6

Form: Powder

Product Application

1.Molecular Biology – Nucleic Acid Extraction & Purification​ (Core Application)

Function: Efficiently degrades proteins (including nucleases) and digests cellular structures, releasing intact nucleic acids while inactivating nucleases​ (DNases and RNases).

2.Proteomics & Biochemistry

Membrane Protein Preparation: Its activity in SDS makes it useful for digesting membrane protein samples prior to mass spectrometry.

Enzyme Removal: Terminates enzymatic reactions (e.g., in vitro transcription/translation) by degrading protein enzymes.

3.Forensics & Paleogenomics

Digests proteins in challenging samples (FFPE tissues, ancient bones, hair, saliva stains) to release trace nucleic acids for analysis.
