Membrane extracts from adult H. contortus were enriched 24-fold for cysteine protease activity by passage over a Thiol-Sepharose affinity column and the proteins obtained (abbreviated as TSBP) were clearly localized to the microvillar surface of the intestinal cells (Knox et al., 1995,1999). TSBP comprised a prominent 60 kDa protein and several minor bands between 35 and 45 kDa and 97 to 120 kDa (Fig. 13.2). Protease activity at 38, 52 and 70 kDa was attributable to cysteine proteases and at 70 and 88 kDa to serine/metalloproteases, as judged by inhibition analyses. Lectin-binding studies showed that most of the TSBPs were glycosylated. Expression library... 

Most previous work on rat MUPs has been conducted with inbred or relatively inbred laboratory rat strains that are likely to exhibit considerably reduced phenotypic variation relative to the wild population, as we see in mice. As an initial exploration of MUP expression, we analysed urine from nine wild-caught male rats captured from several different populations in northern UK by isoelectric focusing electrophoresis (IEF). The protein banding pattern was very similar between individuals, consisting of two major and several minor bands. Peptide mass... 

In other experiments with the same pellet, pyridine (Py) was sorbed by the surface at room temperature and, after a few minutes, the residual gaseous Py was removed by pumping at room temperature. The compensated spectrum (Fig. 11) then showed the strong bands at 1542 and 1485 cm l as well as minor bands,... 

Photoelectron spectroscopy has been used to study equilibria in the gas phase. Thus, the taut-omerism of triazoline-5-thione is studied by variable temperature photoelectron spectroscopy <83CJC1197). PhotoeleCtron spectra of 1,2-dimethyltriazoline-5-thione (67a) calibrated with the Pi/2 and Ps/2 lines of argon and xenon are recorded with a resolution of 30 meV. The spectra of freshly evaporated material obtained with a Pj probe indicate the presence of the unchanged thione even at 160 °C. A spectrum recorded with a P2 probe after heating the evaporated sample to 160 °C exhibits an additional minor band at 9.40 eV which is most likely due to 2-methyl-4-methylthiotriazole (67b). 

Gadolinium may be measured in an acidic solution by flame or furnace atomic absorption or ICP atomic emission spectropbotometry. Also, gadolinium may be identified nondestructively and rapidly by x-ray fluorescence methods. It also may be measured by neutron activation analysis, and by various spectrophotometric techniques. The element shows sharp absorption bands in ultraviolet region at 270-280 nm. Other lanthanides also produce bands in this region however, those are low intensity minor bands. 

After removal of solvent in vacuo, the yellow residue is chromatographed on silica thin layer chromatography (TLC) plates using hexane-CH2Cl2(85 15) as eluent. The major product, 2, is a nearly colorless band observed at Rf = 0.17. This band can be seen better by using an UV lamp and UV sensitized TLC plates (precoated TLC plates, silica gel 60 F-254, layer thickness 0.25 mm, Merck). This band is separated from the starting material (Rf = 0.47) and several minor bands and the products are eluted from the silica gel with CH2C12. An analytically pure sample can be obtained by recrystallization from hexane at - 20 °C. Yield 0.053-0.070 g (30-40%). 

In the search for a Ca2+ independent a-LTX receptor, affinity chromatography in the absence of Ca2+ was used to isolate brain proteins with any affinity for a-LTX. Sequencing of all proteins in the a-LTX column eluate (Krasnoperov et al. 1996 Krasnoperov et al. 2002b) has revealed that, in addition to LPH1, PTPg can also bind to the column as a set of two minor bands. 

It is evident from Fig. 5 that, as the potential becomes yet more positive in an n-type material, the Fermi level will approach the VB. It might be expected that, under these circumstances, the minority band would become...
