The best purification degree of enzyme solutions is observed upon application of A500P anion-exchange
resin at pH 4.
All the anion-exchange
reactions were carried out at 45[degrees]C for 2 h.
An optimized PCR procedure and a high performance anion-exchange
liquid chromatography were employed in this research.
Glyphosate and AMPA analysis in sewage sludge by LC-ESI-MS/MS after FMOC derivatization on strong anion-exchange
resin as solid support.
Purity of the sample obtained after the anion-exchange
chromatography was assessed by SDS-PAGE and a single protein band with an approximate molecular mass of 25 kDa was observed (Figure 2A).
Research of influence of trimethylamine quantity on size of anion-exchange
resin exchange capacity showed that the maximum degree of amination of polymer is reached at 4 multiple surplus of amine.
Key words Anion-exchange
In view of these drawbacks, high performance anion-exchange
chromatography has increasingly been used for carbohydrate determination.
3] sample was dispersed in 400 ml of carbonate-free aqueous solution of corresponding acid neutralized by NaOH solution; an excess of intercalated anion was used with respect to the LDH anion-exchange
capacity (concentration of 0.
Until now, the methods have required separate isoformseparation and transferrin-quantification steps, such as isoelectric focusing and immunofixation, or anion-exchange
column chromatography and immunoassay.
We are grateful to Dr Caixan Tang of La Trobe University for providing the seed, Greg Codes for the access to the field site, and Dr Maartin Hens, CSIRO Plant Industry, for assistance with the anion-exchange
Trypanosoma brucei: miniature anion-exchange
centrifugation technique for detection of low parasitaemias: adaptation for field use.
Cheap and effective fuel cells are achievable using alkaline anion-exchange
membranes, according to a scientist from the UK's University of Surrey.
membranes to measure soil nitrate availability and net nitrification.
Building on that first step, DuPont worked with colleagues to design a novel technique for sorting CNTs using anion-exchange
chromatography and single-stranded DNA.
