Summary

Porter's numbering has been retained: the first figure is a running number and the second figure represents the year.

(434/52, 436-7/52) Three slides of phase diagrams similar to those illustrated by R.R. Porter, 'The partition chromatography of enzymes' (Bibliog. 10). Such phase diagrams are obtained by mixing water, salt and organic solvent in different proportions and looking for the appearance of opalescence. The aim is to find optimal conditions for partition chromatography.

(287/53) Partition 'Chromatogram of ribonuclease', fig. 2 in A.J. Martin and R.R. Porter, 'The chromatographic fractionation of ribonuclease' (Bibliog. 4)

(288/53) 'Crude penicillinase', partition chromatography of the enzyme, penicillinase; fig. 11 in R.R. Porter, 'The partition chromatography of enzymes' (Bibliog. 10)

(289/53) 'Phase diagram of the system ammonium sulphate-water-ethylene glycol monoethyl ether at 20°', fig. 1 in A.J. Martin and R.R. Porter, 'The chromatographic fractionation of ribonuclease' (Bibliog. 4)

(290/53) 'Crystalline trypsin', partition chromatography of the enzyme, trypsin; fig. 10 in R.R. Porter, 'The partition chromatography of enzymes' (Bibliog. 10)

(292/53) 'Activated chymotrypsinogen', partition chromatography of the activated enzyme, fig. 9 in R.R. Porter, 'The partition chromatography of enzymes' (Bibliog. 10)

(411/54) 'Separation of ribonuclease from crude extract of beef pancreas', ion exchange chromatography of the enzyme, ribonuclease; fig. 2 in R.R. Porter, 'Chromatography of proteins' (Bibliog. 7)

(413/54) ion exchange chromatography of the enzyme, chymotrypsinogen

(415/54) 'Fractionation of lysozyme carbonate on amberlite IRC-50', ion exchange chromatography of the enzyme, lysozyme; fig. 3 in R.R. Porter, 'Chromatography of proteins' (Bibliog. 7)

(417/54) elution of unidentified proteins at increasing sodium chloride molarity; probably adsorption chromatography - see Bibliog. 7

(441/54) system for partition chromatography at sub-zero temperatures
