Fast Immunoassay for Microfluidic Western Blotting by Direct Deposition of Reagents onto Capture Membrane

Western blotting is a widely used protein assay platform, but the technique requires long analysis times and multiple manual steps. Microfluidic systems are currently being explored for increased automation and reduction of analysis times, sample volumes, and reagent consumption for western blots. Previous work has demonstrated that proteins separated by microchip electrophoresis can be captured on membranes by dragging the microchip outlet across the membrane.
This process reduces the separation and transfer time of a western blot to a few minutes. To further improve the speed and miniaturization of a complete western blot, a microscale immunoassay with direct deposition of immunoassay reagents has been developed. Flow deposition of antibodies is used to overcome diffusion limited binding kinetics so that the entire immunoassay can be completed in 1 h with detection sensitivity comparable to incubation steps requiring 20 h. The use of low microliter/min flow rates with antibody reagents applied directly and locally to the membrane where the target proteins have been captured, reduced antibody consumption ~30-fold. The complete western blot was applied to the detection of GAPDH and β-Tubulin from A431 cell lysate.

Establishment of a candidate equine influenza Florida Clade 2 strain A/eq/Richmond/1/07 horse antiserum as Ph. Eur. Biological Reference Preparation/OIE International Reference Reagent

Equine influenza (EI) is an important respiratory disease of horses, with welfare and economic consequences. Vaccination remains one of the most efficient prevention methods available. Equine influenza virus (EIV) is constantly evolving and consequently EI vaccines need to be updated on a regular basis. In 2010, the World Organisation for Animal Health (OIE) Expert Surveillance Panel (ESP) on EI provided a new recommendation for EI vaccine strain composition, including the incorporation of representative EIV strains of both Florida Clade 1 and Clade 2 sub-lineages (FC1 and FC2, respectively). In this context, the European Pharmacopoeia (Ph. Eur.) – OIE reference panel for EI had to be complemented by an antiserum raised in horses against the FC2 representative EIV strain A/eq/Richmond/1/07.
An international collaborative study was organised and managed by the European Directorate for the Quality of Medicines and HealthCare (EDQM) within the framework of its Biological Standardisation Programme (BSP). The study aimed at evaluating a new candidate reference for use as a common OIE International Standard/Ph. Eur. Biological Reference Preparation (BRP) horse antiserum to FC2 EIV A/equine/Richmond/1/07.
The standard was to be established using the SRH and HI tests for subsequent use in immunogenicity, efficacy and batch potency assay of EI vaccines as a Ph. Eur. BRP (Ph. Eur. monograph 0249) and for use in clinical diagnostic tests as an OIE-approved International Standard Reagent (OIE chapter 3.5.7). The collaborative study confirmed the suitability of the candidate and an SRH titre was assigned. The candidate was adopted as a BRP by the Ph. Eur. Commission and approved by the OIE Biological Standards Commission as an International Standard Serum in November 2017 and February 2018, respectively.

Selective phase transfer reagents (OxP-crowns) for chromogenic detection of nitrates especially ammonium nitrate

Nitrogen and phosphorus-containing ions such as ammonium, nitrates and phosphates are anthropogenic pollutants while ammonium nitrate may be diverted for nefarious purposes in improvised explosive devices. Crown ether-oxoporphyrinogen conjugates (OxP-crowns) are used to selectively detect nitrates, especially their ion pairs with K+ and NH4+, based on ion pair complexation of OxP-crowns under phase transfer conditions.
The presence of phosphate and carbonate lead to deprotonation of OxP-crowns. OxP-1N18C6 is capable of extracting ion pairs with nitrate from aqueous phase leading to a selective chromogenic response. Deprotonation of the OxP moiety leads to [OxP-]-1N18C6[K+] and is promoted by crown ether selective cation binding coupled with hydration of basic oxoanions, which are constrained to remain in the aqueous phase.
This work illustrates the utility of molecular design to exploit partitioning and ion hydration effects establishing selectivity of chromogenic response.
