High performance liquid affinity chromatography (HPLAC) is a useful procedure to investigate he interactions between carbohydrate binding protein and their ligands. Technical requirements are similar to conventional HPLC. HPLAC can screen and separate natural ligands from complex biological mixtures.

Protocol for configuration, column construction, and column packing for a capillary liquid chromatography system. Protocol describes a procedure for adapting conventional HPLC systems to provide accurate low-flow rates (0.4-4 µl/min) and gradients required to operate slurry-packed capillary columns. A key component of this system is a commercial axial-beam longitudinal flow cell that can be fitted to several commercial UV detectors. - [Read Configuration Column Construction Column Packing for Capillary Liquid Chromatography]

Protocol for desalting of peptides and protein mixtures by RP-HPLC techniques. The RP-HPLC technique can be used to "desalt" peptide or protein samples derived from extraction procedures, from chemical reactions such as reductive alkylation in the presence of urea or guanidine hydrochloride, citraconylation, iodination, or cyanogen bromide cleavage, or recovered from other chromatographic separation. - [Read Desalting of Peptides and Protein Mixtures by RP-HPLC Techniques Protocol]
High-resolution SNP mapping by denaturing HPLC. A SNP mapping procedure that relies on resolving polymorphisms by denaturing HPLC without the necessity of determining the nature of the SNPs. They demonstrate the use of denaturing high-performance liquid chromatography to identify mutations in the candidate genes and to fine-map chromosomal breakpoints. - [Read High-resolution SNP mapping by denaturing HPLC]

Gliotoxin is a metabolite of Aspergillus fumigatus that exhibits immunosuppressive activity against certain cells of the immune system. Secretion of gliotoxin during infection has been suggested as being a factor in the pathogenesis of aspergillosis. Gliotoxin secretion can be assayed in a number of ways by thin layer chromatography (TLC) high performance liquid chromatography (HPLC) or bioassay using the effect of gliotoxin on human cells1. - [Read Method for Assaying Gliotoxin Production in Aspergillus fumigatus Protocol]

Laboratory sample cleanup is a necessary part for analytical preparation analysis. The removal of Contaminants such as proteins, cell debris and other materials is an important step. Typically this has been done by using Acetonitrile and then Centrifugation to pellet the debris leaving the clean supernant. After this process supernatant can be used for further analysis by HPLC, GC, MS and other analysis tandem methods. HTS Labs. - [Read Protein Precipitation Microplate]
Protocol details the purification and analysis of many synthetic peptides of 2-65 amino acid residues. These peptides contain a number of ionizable or polar side chains, but do not contain secondary structural elements (such as ß-sheets) that favor supramolecular assembly. - [Read Purification of Peptides from Solid-Phase Peptide Synthesis with RP-HPLC Protocol]
