[More] In an effort to extend automated Edman degradation to nanomole quantities of protein, the method of sequenator analysis described by Edman and Begg (Edman, P., and Begg, G. (1967), Eur. J. Biochem. 1, 80) was modified to permit long degradations in the absence of carrier proteins. By using an aqueous 0.1 M Quadrol program with limited, combined benezene-ethyl acetate solvent extractions, as well as a change in the delivery system for heptafluorobutyric acid, it was possible to recover and identify the first 30 amino acid residues from a sequenator run on 7 nmol of myoglobin. For 3 nmol of myoglobin, 20 steps could be identified. PTH-amino acids were identified by gas-liquid chromatography and thin-layer chromatography on polyamide sheets. Without using a carrier protein the cup to prevent mechanical losses (Niall, H. D., Jacobs, J. W., Van Rietshoten, J., and Tregear, G. W. (1974), FEBS Lett. 41, 62), the repetitive yield using this program was 93-96%. The same program has been applied successfully to peptides of 14 or more residues with or without modification by Braunitzer's reagent and to a number of larger peptides and proteins including a 216 residue segment of rabbit antibody heavy chain in which a sequence of 35 steps was accomplished on 25 nmol.

[More] A simple procedure is described for converting thiazolinones, from the protein sequenator, to the more stable phenylthiohydantoins without using the conventional HCI conversion procedure. The thiazolinones are applied to a silica gel plate and converted to phenylthiohydantoins by heating at 140 for 5-10 min, in the presence of heptafluorobutyric acid, prior to chromatography. After chromatography, measurements of the yields of the derivatives on the plate can be made with a variable-wave-length thin-layer chromatography scanner. This is shown to be a useful adjunct for identifications.

[More] IPA COPYRIGHT: ASHP A gas chromatographic method for the determination of pentazocine and its metabolites in human plasma and urine is described. The determination of plasma pentazocine involves the extraction of pentazocine and a suitable internal standard, the derivatization of these compounds with heptafluorobutyric acid anhydride, and the chromatography of the derivatives using tritium foil, electron capture detection. The determination of urinary pentazocine and the trans-alcohol and trans-acid metabolite involved the extraction of the compounds and an internal standard, derivatization with a silylating reagent, and the chromatography of the derivatives using flame-ionization detection. The determination of the cis-alcohol metabolite involved adsorption chromatography followed by the same derivatization and chromatographic analysis as used for the trans derivatives. The lower limit for the quantitative procedure described was found to be about 0.1-0.2 mcg./ml. for pentazocine and its hydroxylated metabolites, and about 1-2 mcg./ml. for the acid metabolites.

[More] PESTAB A method was developed for determining chlorobenzilate as a derivative of heptafluorobutyric acid, using GLC-ECD. The method was applied to determination of residues in fruits and vegetables. Chlorobenzilate is extracted with acetonitrile, transferred to n-hexane, cleaned up on a Florisil column, and treated with heptafluorobutyric acid in the presence of a catalyst; the derivative formed is washed and determined. The GLC-ECD conditions are: glass column 4 mm i. d. , 1000 mm long, packed with 5% SE-30; detector temperature 210 DEG C, ECD with tritium-labeled foil. Recoveries of 88. 6% and 91. 1% were obtained from radish and strawberry fortified with 0. 05 ppm of chlorobenzilate, 84. 1% from Satsuma orange fortified with 0. 1 ppm, and 93. 6% from summer orange pulp fortified with 0. 05 ppm. The same analytical procedure but without the reaction with heptafluorobutyric acid showed a sensitivity only one sixteenth of that obtained when the reaction mentioned was included in the procedure.
