(Running title): overview of silver staining methods for proteins ABSTRACT On the basis of the physico-chemical principles underlying silver staining of proteins, which are recalled in this paper, several methods of silver staining of proteins after SDS electrophoresis in polyacrylamide gels or isoelectric focusing were tested. The most valuable protocols are presented in this report, including...
Suspension-cultured cells derived from immature embryos of winter wheat (Triticum aestivum L. cv. Chihoku) were used in experiments designed to obtain clues to the mechanism of the ABA-induced development of freezing tolerance. Cultured cells treated with 50 microM ABA for 5 d at 23 degrees C acquired the maximum level of freezing tolerance (LT50; -21.6 degrees C). The increased freezing tolera...
Chloride ion (Cl-) secretion by the rabbit corneal epithelium involves a catecholamine-stimulated Cl- conductance at the apical membrane, but the characteristics of the ion channel(s) responsible are unknown. A primary cell culture system was developed that induces stratified epithelial differentiation of rat and rabbit corneal epithelial cells, as detected by differential interference contrast...
Sophora alopecuroides lectin (SAL), a novel lectin from the seeds of Sophora alopecuroides, was purified by ion-exchange chromatography on diethylaminoethyl (DEAE)- and carboxymethyl (CM)-Sepharose columns, followed by gel filtration on a Sephadex 75 10/300 GL column. SAL was found to be a monomer of 39916.3 Da, as determined by tricine-sodium dodecyl sulphate-polyacrylamide gel electrophoresis...
Lactobacillus plantarum 423, isolated from sorghum beer, produces a bacteriocin (plantaricin 423) which is inhibitory to several food spoilage bacteria and food-borne pathogens, including Bacillus cereus, Clostridium sporogenes, Enterococcus faecalis, Listeria spp. and Staphylococcus spp. Plantaricin 423 is resistant to treatment at 80 degrees C, but loses 50% of its activity after 60 min at 10...
The amount of oxidative phosphorylation enzymes in mitochondrial encephalomyopathy patients has been studied by two-dimensional electrophoresis (blue native PAGE/Tricine-SDS-PAGE). Only 20 mg muscle was required to identify and analyse complexes I, III, IV, and V after Coomassie staining. In most cases reduced amounts of the involved complex(es) correlated well with decreased enzyme activities....
A Bacillus species, EMD4, with strong antibacterial activity was isolated from ganjang (soy sauce) and identified as B. subtilis. B. subtilis EMD4 strongly inhibited the growth of B. cereus ATCC14579 and B. thuringiensis ATCC33679. The antibacterial activity was stable at pH 3-9 but inactive at pH 10 and above. The activity was fully retained after 15 min at 80°C but reduced by 50% after 15 min...
Rheumatoid arthritis (RA) has been attributed to the abnormal production of cytokine interleukin-6 (IL-6), which has a variety of physiological activities. In vivo IL-6-receptor imaging provides useful suggestions regarding the mechanism of anti-IL-6-receptor antibody action and indicates a basic therapeutic strategy for treating RA. Therefore, this study was designed to establish a method for ...
OBJECTIVE To screen, identify, and compare the serum biomarkers between anovulatory dysfunctional uterine bleeding (ADUB) and ovulatory dysfunctional uterine bleeding (ODUB) in Lizu females. METHODS The subjects included 128 ADUB patients, 63 ODUB patients, and 93 controls. The serum and supernate of the subjects' mense were collected and stored at -80 °C until use. Differential proteins in t...
Intact mitochondria, obtained from Euglena gracilis Klebs var. bacillaris Cori mutant W10BSmL, which lacks plastids, and purified on Percoll density gradients, form adenosine 3'-phosphate 5'-phosphosulphate from sulphate. The optimal conditions include addition of 17 mM-Tricine/KOH, pH 7.6, 18 mM-MgCl2, 250 mM-sucrose, 5.66 mM-sodium ADP (or 0.94 mM-sodium ATP), 1 mM-K2SO4, carrier-free 35SO4(2...
