A compact apparatus (11) for the N-terminal and C-terminal sequencing of proteins and peptides is disclosed. The apparatus comprises a heated coupling and reaction chamber (RC) to accommodate a reaction cartridge such as a CFR containing a peptide sample (S) for sequential reaction with a plurality of reagents (R1 R2, and , R3), and solvents (S1 and S2). A multi-inlet valve (VMI) controls flow of the reagents and solvents to the reaction chamber and a, transfer valve (VT) controls flow of fluids from the reaction chamber either to waste or to a conversion flask confined within a heated conversion chamber (CC). The conversion products are then conveyed through a selector valve (VS) and a …

Why it's free to use
- Filed February 8, 1990. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended February 8, 2010.

- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
