Objective: The aim of this study is to investigate the neuroprotective effect chrysotoxine (CTX) on sevoflurane-treated nerve cells and uncover potential regulation mechanism. Methods: Nerve treated with sevoflurane CTX were subjected MTT apoptotic detection. Cell apoptosis oxidative stress detected by flow cytometry (FCM) ELISA assays. In addition, immunoblot assay was performed signaling path...

The nucleoprotein of Lassa virus, strain Josiah, was expressed in Escherichia coli as an N-terminally truncated, histidine-tagged recombinant protein. Following affinity purification the protein was completely denatured and spotted onto nitrocellulose membrane. A total of 1 microgram of protein was applied for detection of Lassa virus antibodies (LVA) in a simple immunoblot assay. Specific anti...

In a study using the current first generation Ortho ELISA, a second generation Ortho ELISA, and the RIBA HCV strip immunoblot assay, all patients who were strongly positive for antihepatitis C virus (HCV) on ELISAs (OD490 > 3) were reactive to RIBA for multiple bands. While all ELISA false positive samples had low or intermediate OD490 values, RIBA confirmed HCV reactivity in 50% of the patient...

METHODS. D407 cells cultured in dishes or Transwell inserts were treated with cobalt chloride or varying doses of IGF-1. Whole cell lysates were assayed by immunoblot for HIF-1 expression, whereas conditioned medium was TCA precipitated and assayed by immunoblot for VEGF and ligand blot for IGFBP-3. Cells grown on coverslips were similarly treated and probed with antibodies to HIF-1 , VEGF, and...
