The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.
Use a concentration of 1 µg/ml. Predicted molecular weight: 59 kDa. Good results were obtained when blocked with 5% non-fat dry milk in 0.05% PBS-T.
RIC8 is a Guanine nucleotide exchange factor (GEF), which can activate some, but not all, G-alpha proteins by exchanging bound GDP for free GTP.
The Caenorhabditis elegans protein Ric-8 has two mammalian homologs that have been identified : Ric-8A (Ric-8/synembryn) and Ric-8B. Synembryns are proteins that positively regulate synaptic transmission.
