peptide sample reconstituted with water containing 0.1% formic acid was separated by a Nano Acquity UPLC system (Waters, USA).
The mCIM substituted 400 [micro]l of water for 2 ml of tryptic
soy broth, adding just 1 [micro]l of organism instead of 10 [micro]l and extending the incubation period from 2 h to 4 h [+ or-] 15 min.
peptide samples were reconstituted in 15 [micro]L of 3% acetonitrile with 0.1% trifluoroacetic acid.
In conclusion, we demonstrated that digested tryptic
protein samples, which contain encrypted peptides, are able to exert an antiproliferative activity on neoplastic cells.
Phosphorylation sites on the detected tryptic
peptides are shown in Figure S2.
Bacterial strains were sub-cultured in Tryptic
Soy Broth (TSB, Merck, Germany) and further incubated for 48 h at 37[degrees]C.
E.tarda can be isolated on Edwardsiella Isolation Media (EIM), Brain Heart Infusion (BHI), Tryptic
Soya Agar (TSA), Xylose Lysine Deoxycholate(XLD) and MacConkey.
Characterization of alpha-casozepine, a tryptic
peptide from bovine alpha(s1)-casein with benzodiazepine-like activity.
Following alkylation, protein solutions were subjected to tryptic
digestion, by the addition of 2.5 Og of sequencing grade porcine trypsin from Promega(R).
In previous works we demonstrated that these complexes have properties that partly overlap those displayed by native ones, being also characterized by an irreversible binding that confers on these complexes a particular resistance to tryptic
Isolation and identification: Samples were inoculated in Tryptic
Soy Broth (TSB) and incubated at 37C for 24 hours.
