High density lipoproteins (HDLs) have been proposed to function jointly with lecithin:cholesterol acyltransferase and CETP to facilitate cholesterol transport from tissues to the liver. This mechanism, referred to as reverse cholesterol transport, is physiologically important because it maintains systemic cholesterol levels. CETP is responsible for neutral lipid transfer activity in plasma in numerous species. Since CETP is able to accelerate specifically the exchange of lipid components between pro- and anti-atherogenic lipoprotein fractions, it may be a key determinant of the global atherogenicity of the plasma lipoprotein profile and arises as a possible target in atherosclerosis prevention. CETP has an important role in reverse cholesterol transport and shaping and affecting the composition of plasma lipoproteins. In general elevated levels of CETP have been associated with increased risk of coronary heart disease.

Elimination of particles from samples prior to HPLC or other chromatographic analysis is essential in order to maintain the integrity of the chromatography column and to maximise its operating life time. Minisart® syringe filters optimised for sample preparation consist of a polypropylene (PP) housing and membrane components featuring maximum chemical compatibility and minimum extractables to ensure excellent results. Due to the typical range of volumes from less than 1 ml to 100 ml these filters are available in three different diameters with an effective filtration area of 0,12, 1,7 and 4,8 cm².

L-Lysine is an essential proteinogenic α amino acid. It contains an N-butyl amino group in the side chain, and this moiety is protonated at physiological pH. In addition, L-lysine is one of the two amino acids that are degraded to give ketone bodies (a ketogenic amino acid).

Activators: Papain is activated by cysteine, sulphide, sulphite and more. It is enhanced when heavy metal binding agents such as EDTA are also present. N-bromosuccinimide enhances the activity. Inhibitors: Substances which react with sulphydryl groups including heavy metals, carbonyl reagents. Aldehydes are papain inhibitors. Benzoylamidoacetonitrile is an inhibitor. See Shapira and Arnon (1967a and b) on antibody inhibitors. Papain may be inactivated by H₂O₂ generated by γ-irradiation of H₂O⁻ the active SH group being oxidised to sulphenic acid. Specific inhibitors are AEBSF, antipain, cystatin, E-64, leupeptin, PMSF, TLCK and TPCK.

DL-Dithiothreitol is also known as Clelands reagent; Protective agent for sulfhydryl groups (-SH). Quantitatively reduces disulfides (-S-S- to -SH). In this reaction the DTT is oxidized to the cyclic disulfide which ensures the reduction of other disulfides in solution. Disulfide reduction occurs quickly at pH 8.
Dithiothreitol is useful for stabilizing sulfhydryl containing enzymes. Effective in sample buffers for reducing protein disulfide bonds prior to SDS-PAGE. DTT can also be used for reducing the disulfide bridge of the cross-linker N,N'-bis(acryloyl)cystamine to break apart the matrix of a polyacrylamide gel. DTT is less pungent and is less toxic than 2-mercaptoethanol.
Useful for stabilizing sulfhydryl-containing enzymes.

CyDye™ DIGE fluors are available as minimal and saturation labeling dyes. The minimal dyes are intended for general 2-D application use where sufficient amounts of sample are available. The saturation dyes from the Scarce Sample Labeling Kit are designed to be used for applications where only small amounts of sample are available, for example in Laser Capture Microdissection.
