Custom Premix Selecting "Custom Premix" option means that all of the beads you have chosen will be premixed in manufacturing before the kit is sent to you.
Native endoproteinase Glu-C from Staphylococcus aureus. Serine protease that specifically hydrolyzes peptide bonds at the carboxylic side of glutamic acid and aspartic acid residues. Inhibited by DFP and α2-macroglobulin. Suggested working concentration: 1:20 to 1:100 (protease:protein by weight) for sequence analysis.

Form
Lyophilized
Recommended reaction conditions
Protocol
1. Dissolve the protein to be digested in buffer (e.g. 25 mM ammonium carbonate, pH 7.8). If the protein requires denaturation, add SDS (≤0.1%), guanidine hydrochloride (≤1 M), or urea (≤1 M) to the digestion buffer. (Note: if urea is used, also include 20 mM methylamine to avoid cyanate ion blockage of the N-terminus substrate protein.
2. Suggested working concentration is 1:20-1:100 (protease:protein by weight for sequence analysis).
3. Incubate for 2-18 h at 25°C.
