Yersinia pestis Recombinants

Abstract Previously, we developed a single recombinant protein vaccine against plague composed of a fusion between the Fraction 1 (F1) capsular antigen and the V antigen. To determine whether the overall expression, solubility, and recovery of the F1 fusion protein -V could be improved, we modified the original fusion. Standard Read more…

Shigella flexneri Recombinants

Introduction The PhoP/PhoQ two-component signal transduction system is an important regulator of stress responses and virulence in most gram-negative bacteria, but the characterization of PhoP/PhoQ in Shigella has not been thoroughly investigated. In the present study, we found that deletion of phoPQ (ΔphoPQ) from Shigella flexneri Recombinants 2a 301 (Sf301) Read more…

Validation Pipette

Abstract We have implemented a simple, inexpensive and rapid procedure for the validation and performance verification of pipettes mounted on automatic liquid handlers (ALH) as required for ISO 17025 accredited laboratories. A serial dilution of six or seven passages of OrangeG in quadruplicate in a flat-bottom 96-well microtiter plate, manually Read more…
