Expression of functional mammal flavocytochrome b558 in yeast: Comparison with improved insect cell system

Functional epitope on human neutrophil flavocytochrome b558.

mAb NL7 was raised against purified flavocytochrome b(558), important in host defense and inflammation. NL7 recognized the gp91(phox) flavocytochrome b(558) subunit by immunoblot and bound to permeabilized neutrophils and neutrophil membranes. Epitope mapping by phage display analysis indicated that NL7 binds the (498)EKDVITGLK(506) region of gp91(phox). In a cell-free assay, NL7 inhibited in v...

Cloning and Expression of Simian Rotavirus Spike Protein (VP4) in Insect Cells by Baculovirus Expression System

Background: VP4 protein is as spikes on rotavirus outer capsid shell which is responsible for virus attachment to the host. VP4 induces production of neutralizing antibodies which could be used for serotyping of different isolates. Methods: Simian rotavirus SA11 gene 4 cDNA was cloned into a cloning plasmid pDONRTM by recombination reaction using clonase II enzyme mix. The resulting clone was c...

Comparison of Enzymatic Method Rapid Yeast Plus System with RFLP-PCR for Identification of Isolated Yeast from Vulvovaginal Candidiasis

Objective(s) To compare two identification methods, i.e., restriction fragment length polymorphism (RFLP)-PCR analysis and enzymatic method Rapid TM Yeast Plus System to identify different species causing vulvovaginal candidiasis (VVC). Materials and Methods Vaginal discharges of women who had attended the gynecology outpatient clinic of Mobini Hospital in Sabzevar, Iran were collected using...

expression of the recombinant plasminogen activator (reteplase) by a non-lytic insect cell expression system

reteplase is a potent thrombolytic agent which is widely used in the management of acute myocardial infarction and stroke. it belongs to the third generation of the thrombolytic drugs and has been derived from native human tissue plasminogen activator by removing three domains of it and keeping the kringle 2 and serine protease domains. however, the high cost of this drug, has limited the appli...
