The primary amino acid sequence of polypeptide is routinely determined using the commercially available gas-liquid-phase sequencers [1, 2] and solid-phase sequencers [3, 4] based on the Mman degradation chemistry [.5j. These instruments can routinely obtain the primary amino acid sequence from 10 to 100 pmol of polypeptide. However, the need for higher sequencing sensitivity remains, as Kent et al. [6] have pointed out that rare proteins may only be present at the 30-300 fmol level on 2D-polyacrylamide gels.

In 1973, Wachter and Machleidt (Wachter et a/., 1973 Machleidt et a/., 1973) described the use of aminoglass supports, which for the first time permitted solid-phase sequencing of proteins. The supports are prepared by silylating controlled-pore glass beads (e.g.. Corning CPG-10,200-400 mesh) with 3-aminopropyltrimethoxysilane (Wachter et a/., 1973) or iV-(2-amino-ethyl)-3-aminopropyltriethoxysilane (Bridgen, 1975) (see Fig. 8). The resulting... 

The design and construction of the solid-phase peptide sequencer have been discussed in detail (Laursen et ai, 1975). Basically, the instrument consists of a thermostatted reaction column, which holds the resin-bound peptide, and a series of pumps and valves that deliver reagents and solvents to the column. After each cycle, the liberated thiazolinones are collected in a fraction collector. The instrument is fully automatic and completes a cycle in 60-90 min, depending on how it is programmed. Solid-phase sequencers based on the design of Laursen (1971 Laursen et a/., 1975) are available from Sequemat, Inc. (Watertown, Massachusetts), LKB Instruments (Rockville, Maryland), and Rank-Hilger (United Kingdom). 

Solid-phase sequencing has great potential for microsequencing, especially of hydrophobic polypeptides. Since the peptide is covalently bound, me-... 

In the future, the technique of solid-phase sequencing will be most aided by improved peptide coupling methods and a reduction in the side reactions of the Edman degradation.
