The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.
1/50 - 1/200. Perform heat mediated antigen retrieval with citrate buffer pH 6 before commencing with IHC staining protocol.
Use a concentration of 1 - 4 µg/ml. Fixation/Permeabilization: PFA/Triton X-100
FunctionEssential for the first step in the synthesis of diphthamide, a post-translational modification of histidine which occurs in elongation factor 2 and which can be ADP-ribosylated by diphtheria toxin and by Pseudomonas exotoxin A. Down-regulation increases extracellular release of proteoglycans, indicating a possible role in the secretion process. Stimulates binding of GNEFR to SEC5.
Tissue specificityWidely expressed with highest levels in small intestine, spleen, thymus, heart, liver and lung.
Sequence similaritiesBelongs to the DPH3 family. Contains 1 DPH-type zinc finger.
