The preparation of L-lysine peptides (Lys,, n = 2-14) from poly-L-lysine is described. Fractionation by ion-exchange column chromatography of poly-Llysine hydrolysates on apreparative scale resulted in 0.2-1.0g quantities of individual members of the poly-Llysine series. The peptides isolated prove

These findings indicate that mycobacterial catalases are present in multiple molecular forms. All of these forms appear to have a lower molecular weight than the previously studied mammalian and bacterial catalases. Studies are currently underway to determine if these zynlogranx can be used. for classification of different nlycobacteria,

## Abstract A thinβlayer chromatographic method on chromatoplates coated with Dowex 50 Γ 8 ionβexchange resin, suitable for the separation of 5 nebramycin components, was developed.
Alkali metals have been determined in many ways, but for trace analysis two methods are normally applied: spectrometry and activation analysis. Both flame emission and atomic-absorption spectrometry are very suitable for the trace analysis of alkali metals. Detection limits in the p.p.b, range 1-3 c
