The occurrence of health-relevant contaminants in water has become a severe global problem. For treating heavy-metal-polluted water, the use zeolite materials been extended over last decades, due to their excellent features high ion exchange capacity and absorbency. aim this study was assess effect heavy metal uptake one purified (PCT) two non-purified clinoptilolite tuffs (NPCT1 NPCT2) aqueous...

Abstract Background As wild poliovirus is eradicated, preventing circulation of vaccine-derived top priority. Our lab developed real-time multiplex PCR assays and deep sequencing methodology to detect characterize OPV strains from stool samples. The method requires gel purification product created viral RNA in However, the process filters out a significant portion Here, we compare gel- vs. DNA-...

prostate-specific antigen (psa) was purified to homogeneity from human seminal plasma by ion-exchange chromatography on a cm-sephadex c-50 and by gel filtration on a sephacryl s-200 column. a single 33-kda protein band appeared in sds-page. high pressure liquid chromatography (hplc) of the purified protein produced a single peak, while isoelectric focusing demonstrated the presence of five diff...

acetone fractionated peroxidase from crude extract of brassica oleracea leaves (cabbage) was purified in three steps on chromatographic columns, using sp-sepharose, deae-sepharose and con a-sepharose. the specific activity of purified main isoenzyme (boc-pod) is 1887 u/mg protein with rz: 3.1, which is 172 times more than the rz of crude extract with 4.3% recovery. the molecular weight of boc-p...

Introduction: The major histocompatibility complex (MHC) is a group of cell surface proteins that are essential for recognizing foreign molecules in human and other mammals. The physiologic function of MHC molecules is the presentation of peptides to T cells. In this study, we evaluated the purification of a class II MHC molecule (HLA-DR) from a human Burkitt′s lymphoma cell line; Daudi...
