Omschrijving: Yeast Extract Powder is a vacuum-dried extract concentrate of Baker's yeast containing the B-complex factors of approximately three times the weight of ordinary dry yeast. This product is a vacuum dried autolyzed yeast extract produced from 100% Baker's yeast. It is a concentrated source of soluble protein components, carbohydrates, and B Complex vitamins natural to yeast. Water soluble portion of autolyzed yeast with intact B-complex vitamins. Yeast extract is a mixture of amino acids, peptides, water soluble vitamins and carbohydrates and can be used as additive for culture media.
Yeast Extract Powder is a highly nutritive medium recommended for plate count of microorganisms in water. It is used as a bacteriological media component for a variety of microorganisms and molecular genetics applications. Also suitable for alternative to beef extract.

Omschrijving: 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.

Omschrijving: Ampicillin sodium salt is a semi-synthetic derivative of penicillin, active as a broad-spectrum antibiotic. It is inactivated by beta-lactamases and for this reason a beta-lactamase inhibitor should be considered when using ampicillin. Against gram-positive bacteria, ampicillin has a similar mode of action as benzylpenicillin; against gram-negative bacteria, it has a similar mode of action as chloramphenicol and tetracyclines. In E. coli it inhibits cell wall synthesis.

Omschrijving: Poly-L-lysine is a positively charged amino acid polymer. Poly-lysine binds to DNA, red cell membrane and any negatively charged protein. It is typically used as a coating substrate for culture dishes, slides, etc. It enhances electrostatic interaction between negatively charged ions of the cell membrane and the culture surface. When adsorbed to the culture surface, poly-lysine increases the number of positively charged sites available for cell binding.

Omschrijving: A modified tripeptide reversible protease inhibitor of trypsin-like proteases and some cysteine proteases including endoproteinase Lys-C, kallikrein, papain, thrombin, cathepsin B, cathepsins H and L, trypsin, calpain, trypsin and plasmin. Little to no inhibition is seen against pepsin, cathepsins A and D and alpha-chymotrypsin. When adjusted for molarity, all three salt forms are equally effective; however, the hydrochloride salt is usually less invasive in biological settings. Leupeptin, because of its aldehyde group, may act as a reducing agent and therefore interfere in protein determinations such as Lowry and, to a lesser extent, Bradford.
