We used two-dimensional polyacrylamide gel electrophoresis and immunoblotting techniques to study serum proteins from a patient with a monoclonal gammopathy. Two-dimensional electrophoresis was optimized for serum proteins with two main goals: (a) to allow the resolution of many serum proteins in both directions, with penetration of the maximum number of proteins in the first dimension; and (b)...

ticks are important ectoparasites which are a considerable threat to human beings and to animals all overthe world. enormous economic losses annually occur in livestock production around the world as a result oftheir existance. one of the ways to control ticks and tick-borne diseases is to introduce resistance to theseectoparasites through immunization. for identification of the putative protec...

northern blots or more extensive analyses using microarrays, can also be used. For these latter methods, the isolation and quantitation of intact total RNA are prerequisites for successfully measuring the level of reduction of the mRNA transcript associated with the siRNA treatment. In this article, we discuss how the Experion automated electrophoresis system, which uses microfluidics technolog...

Studies had been attempted to define the mycobacterial antigens by standard biochemical and immunological techniques. One particular antigen, a 65-kilodalton (KDa) protein, is present in a wide range of mycobacterial species and has been most intensively studied. It is designated as 65K antigen or the cell wall protein a (CWP-a) antigen, since it appears to co-purify with cell walls. The 65K an...

Hybridization to genomic DNA fractionated by CHEF electrophoresis can vary >100-fold if the DNA is acid depurinated prior to Southern blotting. The level of hybridization is high or low depending on whether the molecule being analyzed migrates at a size coincident with or different from the size of the majority of genomic DNA in the sample, respectively. Techniques that avoid acid depurination ...

Production of the OXA-23 carbapenemase is the most common reason for the increasing carbapenem resistance in Acinetobacter spp. This study was conducted to reveal the genetic basis of blaOXA-23 dissemination in Acinetobacter spp. in China. A total of 63 carbapenem-resistant OXA-23-producing Acinetobacter sp. isolates, representing different backgrounds, were selected from 28 hospitals in 18 pro...

AIMS To develop a DNA based plate hybridisation assay for the detection of polymerase chain reaction (PCR) products amplified from Aspergillus fumigatus DNA; and to determine the sensitivity of this technique and compare it with Southern blotting. METHODS A half-log dilution series of DNA extracted from A fumigatus was amplified with specific primers, one of which was 5' end labelled with bio...

Preparation of samples for sodium dodecyl sulphate polyacrylamide gel electrophoresis routinely involves heating the protein in solution containing detergent and reducing agent for at least two minutes. Here we show that this treatment causes fragmentation of the protein glycogen phosphorylase, whether purified or as a component of a skeletal muscle preparation. The fragments are detected as mi...

Abstract Background Both the highly pathogenic avian influenza (HPAI) H5N1 and low (LPAI) H9N2 viruses have been reported to cross species barriers infect humans. can cause severe damage are associated with a high mortality rate, but do not such outcomes. Our purpose was use proteomics technology study differential expression of mitochondrial-related proteins related virus infections. Methods A...
