The pH is an important parameter controlling many metabolic and signalling pathways in living cells. Recombinant fluorescent pH indicators (pHluorins) have come into vogue for monitoring cellular pH. They are derived from the most popular Aequorea victoria GFP (Av-GFP). Here, we present a novel fluorescent pH reporter protein from the orange seapen Ptilosarcus gurneyi (Pt-GFP) and compare its properties with pHluorins for expression and use in plants. - [Read A Novel Fluorescent pH Probe for Expression in Plants]

Protocol for detection of autoantibodies with self-assembling radiolabeled antigen tetramers. Details how to produce radiolabeled antigen-streptavidin tetramers for detection of antibodies by immunoprecipitation. Optionally, the antigen tetramers can be denatured to compare responses to folded and unfolded antigen in the same system. This technique can be applied to a large or small number of samples, and a given sample can be simultaneously assayed with multiple antigens. - [Read Detection of Autoantibodies with Self-Assembling Radiolabeled Antigen Tetramers Protocol]

Erythrophagocytosis Assay. The erythrophagocytosis assay is performed to compare the phagocytic rate with and without anti-eythrocyte antibody in either macrophages from control animals or virus-infected counterparts.

Category: Western Blot Protocols: General Western Blot Methods Protocols

For immunoblotting experiments, it is often important to compare the total amount of an antigen from many different sources or to learn if a particular source has the antigen under study.  In the approach described here, tissue cultures, bacteria, yeast cells, tissues, and other sources of antigens are disrupted directly in an electrophoresis sample . - [Read Immunoblotting: Preparing Cell Lysates Protocol]
