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]

Recombinant protein or a chemically synthesized bioactive fragment is immobilized on resin and used as a probe to capture interacting proteins directly from a cell extract.  Affinity-purified proteins are fractionated by gel electrophoresis and visualized by Coomassie staining.  Proteins that interact specifically are identified by comparing this gel profile to one obtained from cell lysates passed over a control resin lacking the immobilized probe protein. - [Read Affinity Purification of Interacting Proteins from Cell Lysates Protocol]

The technique of JC-1 staining has been developed with the intent to detect DY in intact, viable cells. For this purpose JC-1 acts as a marker of mitochondrial activity, since the formation of J-aggregates, which give red emission, is reversible. Cells with high DY are those forming J-aggregates, thus showing high red fluorescence. On the other hand, cells with low DY are those in which JC-1 maintains (or re-acquire) monomeric form, thus showing only green fluorescence. - [Read Analysis of Mitochondrial Membrane Potential with the Sensitive Fluorescent Probe JC-1]

Detection of Phosphatidylserine Externalization During Apoptosis. Shailaja Kasibhatla et al. An early event in apoptosis is the externalization of phosphatidylserine (PS), a phospholipid normally restricted to the inner leaflet of the plasma membrane. This apoptotic event can be monitored using Annexin V, a PS-specific binding protein. This protocol uses Annexin V-FITC as a probe, but Annexin V-biotin is also available, and binding can be revealed using streptavidin-FITC or oth - [Read Detection Of Phosphatidylserine Externalization During Apoptosis (Subscription Required)]

Protocol for fluorescence in situ hybridization of a repetitive DNA probe to human chromosomes in suspension. Hybridization technique which does not need formamide and dextran sulfate. As a model system, we used the repetitive specific human DNA probe pUC 1.77, labeled it with digoxigenin-11-dUTP by nick-translation, and hybridized it to metaphase chromosomes in suspension. These chromosomes were isolated by standard techniques from human lymphocytes. - [Read Fluorescence In Situ Hybridization of a Repetitive DNA Probe to Human Chromosomes in Suspension]
