Bacterial Cell Wall Precursor Phosphatase Assays Using Thin-layer Chromatography (TLC) and High Pressure Liquid Chromatography (HPLC) [PDF]

open access: yesBio-Protocol, 2018
Peptidoglycan encases the bacterial cytoplasmic membrane to protect the cell from lysis due to the turgor. The final steps of peptidoglycan synthesis require a membrane-anchored substrate called lipid II, in which the peptidoglycan subunit is linked to ...

Prediction of peptide retention times in high-pressure liquid chromatography on the basis of amino acid composition

open access: greenProceedings of the National Academy of Sciences of the United States of America, 1980
Analysis of peptides by reverse-phase high-pressure liquid chromatography would be simplified if retention times could be predicted by summing the contribution to retention of each of the peptide's amino acid side chains.

Separation of the natural retinoids by high-pressure liquid chromatography [PDF]

open access: yesJournal of Lipid Research, 1978
A reverse phase high-pressure liquid chromatography system for rapid separation of various retinoids (vitamin A and its analogs) with little or no degradation is described. This method permits detection of as little as 22 pmol of retinoic acid.
