[Cloning and bio-informatics analysis of the CsCrSP from Clonorchis sinensis].

OBJECTIVE: To screen cDNA library from Clonorchis sinensis for gene identification, and to clone and construct library of secreted recombinant proteins. METHODS: cDNA library from Clonorchis sinensis was screened for identifying new genes by Blastn protocol, the sequence of which was further analyzed by Motifscan and NCBI Conserved Domain Search protocol. RESULTS: The secreted proteins (Pcs004f03) were identified, with a 689 bp DNA sequence (187aa), and a theoretical molecular weight of Mr 21100. It is predicted that the gene CsCrSP contains one N-glycosylation site, three N-myristoylation sites, three casein kinase II phosphorylation sites, one cAMP-and cGMP-dependent protein kinase phosphorylation site and protein kinase C phosphorylation site, a signal peptide at N-terminals and SCP-like extracellular protein domain. CONCLUSION: The CsCrSP gene is a secretory cysteine-rich protein with a SCP-like extracellular protein domain.

[Solid/liquid interfacial in situ IR microscope and step-scan time-resolved FTIR spectroscopy and applications in studies of nanomaterials].

Electrochemical in situ microscope IR reflection spectroscopy and step-scan time-resolved FTIR reflection spectroscopy were established by using an IR-plan advantage microscope and a Nexus 870 FTIR instrument, and a home-made signal synchronizer that harmonizes electrode polarization potential and step-scan spectral data collection sequence. These new techniques have been applied in studies of particular IR properties of 2-dimensional nanomaterials. By applying a treatment of fast potential cycling with different time (tau), a set of nanostructured Pt microelectrodes were prepared. CO adsorption was employed as a probe reaction together with in situ developed microscope FTIR spectroscopy. The results illustrated the variation of abnormal IR features with the nanostructure and the thickness (i.e., the size) of film formed on Pt microelectrode, i.e., following the increase of tau in fast potential cycling treatment, the direction of CO band was turned from absorption to antiabsorption direction, and the intensity and the width of CO band were increased. By taking the advantage of the abnormal infrared effects of nanostructured Pt microelectrode, the sensitivity of in situ IR reflection spectroscopy has been significantly improved, and spectra of time-resolution as fast as 50 micros have been recorded at solid/liquid interfaces. The current studies demonstrated not only the success of development of new techniques of in situ IR spectroscopy, but also the exploitation of the established techniques in studies of nanomaterials.
