An electrophoretic study of crystalline preparations of a streptococcal proteinase and its precursor established their isoelectric points at pH values of 8.42 and 7.35 respectively (ionic strength 0.10). Preparations of the proteinase appeared to be electrophoretically homogeneous over a pH range of 5 to 8.5. Precursor preparations contained a relatively low concentration of the active enzyme v...

In the preceding paper on the behavior of pooled normal human serum albumin in various buffers at pH 4.0 (1)) it was demonstrated that the electrophoretic pattern of albumin shows a single moving boundary in the presence of the lower fatty acids, excepting formic and acetic acid, and of certain diand tribasic organic acids. This phenomenon is probably a consequence of the interaction between th...

1. Sera of animals immunized against Japanese B encephalitis, Venezuelan equine encephalomyelitis, and Western equine encephalomyelitis viruses were fractionated by electrophoresis. 2. Electrophoretic patterns of rabbit sera before and after immunization against Japanese B virus showed no consistent change traceable to antibody formation. 3. To determine the antibody content, the electrophoreti...

introduction: differential diagnosis of potential pathogenic entamoeba histological from non-pathogenic entamoeba dispar by a molecular method. material and methods: one pair of primers designed based on sequence of genomic dna coding the 30kd surface antigen of e.histolytica/e.dispar. a 374 base pair pcr product was amplified by using the primers. electrophoretic patterns of pcr product digest...

Investigating the effect of chemical functionalization on MWCNTs' electronic properties, and their influence course results electrophoretic deposition process.

     The purpose of this study was to investigate the deposition of the hydroxyapatite (HA) coating via the electrophoresis procedure. The HA deposition was performed in an ethanol, methanol, acetone and isopropanol suspension. Methanol was found to be the best deposition media. Among the different environmental conditions, including the encapsulation of the samples under two vacuum types of pr...

The potential to reconstitute the whole erythropoiesis of a genetically anemic (WB X C57BL/6)F1-W/Wv (WBB6F1-W/Wv) mouse for at least 8 weeks was compared between 5-fluorouracil (5FU)-treated and nontreated bone marrow cells. C57BL/6-Pgk-1b/Pgk-1a female mice, in which each stem cell had either A-type or B-type phosphoglycerate kinase (PGK) owing to the random inactivation of one of two X chrom...

Early studies on rat haemoglobins indicated the existence of several components (Gratzer & Allison, 1960). Seven components were found in the blood of adult random-bred Wistar rats by CM-cellulose chromatography; their rates of synthesis appeared unaltered during erythroid cell maturation (Brada & Tobiska, 1964). A 5-component electrophoretic pattern found in some randombred Wistar rats was con...
