Omschrijving: Dextran sulphate is a polyanionic derivative of dextran produced by esterification of Dextran with chlorosulphonic acid. Dextran sulphate sodium (DSS) is the sodium salt which is a white to off-white powder freely soluble in water and salt solutions to form a stable, clear solution. The sulphur content is approximately 17% which corresponds to an average of 1.9 sulphate groups per glucosyl residue of the dextran molecule.

Omschrijving: L-Histidine has been used to study cultures of the human T-lymphoblastic leukemia cell line MOLT-4 to study modulation of apoptosis. Exogenous histidine has been shown to enhance the biosynthesis of lovastatin by cultured Aspergillus terreus. Histidine has been utilised as a single nitrogen source to probe swarming in Pseudomonas aeruginosa on agar. An in vivo study has used L-histidine to diminish the net secretory response of the small intestine of of cholera toxin-challenged mice.
