Proteinase K, Molecular Biology Grade – 2 ml

RM449.00
Brand:

New England Biolabs

Proteinase K is a subtilisin-related serine protease that hydrolyzes a variety of peptide bonds and is frequently used to cleanup enzymatic reactions or cell lysates.

  • Highly characterized for more consistent performance
  • Optimal activity and stability for up to 24 months
  • Active in a wide range of temperatures and buffers with optimal activity between 20 and 60°C and a pH between 7.5 and 12.0.
  • No detectable endonuclease, exonuclease, DNase or RNase contaminating activities

Trypsin-digested BSA MS Standard (CAM-modified) – 500 pmol

RM443.00
Brand:

New England Biolabs

This standard is a complex mixture of peptides produced by the tryptic digest of reduced and alkylated Bovine Serum Albumin (BSA).

  • Used to standardize MALDI-TOF or ESI mass spectrometers (TOF, Q-TOF, Ion Trap, or Orbitrap)
  • Standardization range of 500-2400 Da
  • Free of salts, glycerol and detergents
  • Supplied lyophilized
  • Optimal stability for up to 24 months

Trypsin-ultra Mass Spectrometry Grade – 100 ug

RM443.00
Brand:

New England Biolabs

Trypsin-ultra, Mass Spectrometry Grade is a serine endopeptidase, which selectively cleaves peptide bonds C-terminal to lysine and arginine residues.  Trypsin-ultra cleaves at Lys-Pro and Arg-Pro bonds at a much slower rate than when Lys and Arg are N-terminal to other residues.

  • Analyze complex proteomes with minimal autolysis
  • Compatible for simultaneous co-digestion with PNGase F (NEB# P0709)
  • Compatible for simultaneous co-digestion with Endoproteinase LysC (NEB# P8109)
  • Suitable for both in-gel and solution digests
  • Supplied lyophilized
  • Optimal activity and stability for up to 12 months
