Bids Are invited for 2,2-Azino-bis(3-ethylbenzothiazoline-6-sulfonic acid) diammonium salt - =98% (HPLC grade), water: 10 mg/mL, clear to slightly hazy, , 2,2-Diphenyl-1-picrylhydrazyl - 2,2-diphenyl-1-picrylhydrazyl is a free radical, which shows hydrogen acceptor ability towards antioxidants. Hence, it is commonly used in DPPH assay for measuring the antioxidant activity of different natural samples such as wine, fruits, herbal tea etc. , DL - Tyrosine - 99% Assay, peptide synthesis: suitable, reaction type: solution phase peptide synthesis , (±)-6-Hydroxy-2,5,7,8-tetramethylchromane-2-carboxylic acid - Trolox, 97%, (±)-6-Hydroxy-2,5,7,8-tetramethylchromane-2-carboxylic acid (Trolox) has been used in 6-hydroxy-2,5,7,8-tetramethyl chromane-2-carboxylic acid equivalent antioxidant assay (TEAC) to determine the total antioxidant capacity of different fruit species. , M-17 Agar - Suitable for microbiology, NutriSelect® Basic, agar, 12.75 g/Lascorbic acid, 0.5 g/Lcasein peptone (tryptic), 2.5 g/Ldisodium ß-glycerophosphate pentahydrate, 19 g/Lmagnesium sulfate hydrate, 0.25 g/Lmeat extract, 5 g/Lmeat peptone (peptic), 2.5 g/Lsoyapeptone (papainic), 5 g/Lyeast extract, 2.5 g/L , MRS Agar - Suitable for microbiology, NutriSelect® Basic,agar, 12 g/Ldiammonium hydrogen citrate, 2 g/Ldipotassium hydrogen phosphate, 2 g/LD(+)-glucose, 20 g/Lmagnesium sulfate, 0.1 g/Lmanganous sulfate, 0.05 g/Lmeat extract, 5 g/Lsodium acetate, 5 g/Luniversal peptone, 10 g/Lyeast extract, 5 g/L , Dicloxacillin sodium salt monohydrate - H2O: 100 mg/mL, Dicloxacillin is a ß-lactamase resistant penicillin similar to oxacillin. Dicloxacillin has in vitro activity against gram-positive and gram-negative aerobic and anaerobic bacteria. It is resistant to penicillinase. It is used to study bacterial cell wall biosynthesis at the level of peptidogylcan cross-linking and to study mechanisms of penicillinase (ß-lactamase) resistance. It is used to study phenylbutazone plasma binding and extracellular
