Objective:To determine the relative and absolute molecular weight of sodium hyaluronate(SH)by SEC and SEC-MALLS methods,and then compare the two analysis methods.Methods:SB806HQ column was used with mobile phases of 0.2 moL·L-1 sodium chloride(containing 0.2%sodium azide),at 35 ℃ with a ...
Therefore, a compound, 3,5-di(1H-indol-6-yl)-4,5-dihydro-1H-pyrazole-1-carboxamide, was synthesized using a mixture of (E)-1, 3-Di(1H-indol-3-yl) prop-2-en-1-one, semicarbazide hydrochloride, and sodium acetate. It was then examined for its anticancer and antimicrobial properties ...

After washing in PBS containing 10% Haemaccel® (Hoechst, Frankfurt, Germany), and 0.1% sodium azide they were incubated for 30 min at 4°C with FITC-labelled goat-anti-mouse antibody (SIFIN, Berlin, Germany). After washing and fix- ation in 1% formaldehyde, cells were analysed on a ...
Materials Contents The protein molecular weight standards are sold in unit sizes of 400 µL. The proteins are provided in a storage solution that contains 10 mM Tris, pH 7.5, 300 mM NaCl, 100 mM dithio- threitol, 2 mM EDTA, 3 mM sodium azide and 50% glycerol. Each protein is ...
rHuTNF-α release and MePEG liberation in PBS In vitro release studies were performed in triplicate in 25 mL of phosphate buffered saline (PBS, 0.05 mol/L, pH 7.4) con- taining 0.2% (w/v) sodium azide. The NP suspensions were continuously stirred in a thermoshake (60 r/min) at 37...
Sodium hydroxide, sodium azide, acetic acid, phosphoric acid, and potassium chloride were purchased from Fisher Scientific Co (Fair Lawn, NJ). Sodium phosphate monobasic, Tris-base, penicillin G, streptomycin sulfate, trypsin from porcine pancreas, urea, and iodoacetamide were purchased from ICN ...
To assess mem- brane leakage, a 250 μl solution containing 500 μM LUVs and the sample of interest in Buffer 1 (10 mM HEPES, 50 mM KCl, 1 mM EDTA, 3 mM sodium azide) was placed in a 2 mm path-length quartz cuvette. ANTS fluorescence was monitored as a function of time at 520...
Sodium azide with 0.02% (w/v) was then added to the emulsions as a microbial preservative. After formation, the emulsions were adjusted to different pH values (3.0–9.0) using either HCl or NaOH solutions to examine the effect of pH. Some of the emulsions were also adjusted to different ...
