We describe five cases of severe a1-antitrypsin (AAT) deficiency to illustrate the importance of visual inspection of electrophoretic patterns of serum proteins. In four patients the diagnosis of AAT deficiency was clinically unsuspected; in the other patient, the electrophoretic pattern was the first clue to confirm the diagnosis. Densitometric scanning of these patterns invariably overestimat...

In the present work, CdSe nanocrystals (NCs) synthesized with a trioctylphosphine surface passivation layer were modified using amphiphilic molecules to form a surface bilayer capable of providing stable NCs aqueous solutions. Such modified nanocrystals were used as a test solute in order to analyze new electrophoretic phenomena, by applying a micellar plug as a separation tool for discriminati...

in this study, we investigated the effect of using large tio2 nanoparticles in the matrix of small nanoparticles to improve the performance of dye-sensitized solar cells (dsscs), as light scatter to increase the light harvesting. the mixed powder was deposited by electrophoretic deposition (epd) on fto (f-sno2 coated glass). it is shown that adding small quantity of larger nanoparticles can enh...

Chromosome-sized DNA molecules of clinical isolates of Torulopsis glabrata were resolved by a pulsed-field electrophoretic method, contour-clamped homogeneous electric fields. With the conditions established in this study, 8 to 12 bands (ranging from 445 to 3,000 kilobases) were observed. There were differences in the intensities and migrations of bands, consistent with T. glabrata being either...

Erythrocyte membranes prepared by repeated washings with water have been shown by Anderson and Turner (1) to contain relatively constant amounts of hemoglobin. The hemoglobin of lyophilized erythrocyte membranes represented about 3 per cent of the total erythrocyte hemoglobin and between 49 and 57 per cent of dry weight of the membranes (1). No differences between the membrane hemoglobin and th...

This review presents a brief outline and novel developments of electrophoretic separation in microfluidic chips. Distinct characteristics of microchip electrophoresis (MCE) are discussed first, in which sample injection plug, joule heat, channel turn, surface adsorption and modification are introduced, and some successful strategies and recognized conclusions are also included. Important achiev...

The findings on electrophoretic analysis of plasma proteins during many weeks of low protein feeding in dogs accord in general with those of chemical analysis as concerns the alterations in plasma albumin and globulin concentrations. Long continued restriction of dietary protein results in decreased albumin levels while plasma globulin concentrations remain essentially normal. The degree of dep...

Present investigation reports the protein quality parameters in mungbean x ricebean (MR) and urdbean (MU) interspecific lines along with checks. Interspecific contained 138.4-230.3 mg/g total soluble proteins, 0.84-2.63 free amino acids, 3.21-7.10 methionine, 0.08-0.15 cysteine 0.67-1.32 tryptophan. Protein fractionation studies revealed 32.6-48.3 (albumins), 153.3- 218.8 (globulins), 2.81-8.30...
