Rabbit anti-Dopamine D2 Receptor (Rat/Human/Bovine+)
cat# RDI-D2DRabr $406.00/vial
Presentation: 100ul neat sera with 0.05% sodium azide).
-at first use, tighten cap, centrifuge 1-2 minutes at 1000 rpm to concentrate material in vial. Recommend making any dilutions in buffers with 0.1-1% BSA and 0.05% sodium azide
Antigen: An Amino terminal, 11 amino acid peptide sequence (24-34AA) near or at the ligand binding domain of rat D2R. This peptide sequence is right before the first membrane spanning domain. The sequence does not show any similarity to the other members of G- coupled receptors. The preptide was coupled to KLH.
Reconstitution: All peptide/antibody received in solution or reconstituted from Lyophilized vials should be stored frozen at -20oC or below in suitable aliquots. It is not recommended to store diluted solutions. Avoid repeated freeze and thaw.
Specificity: the 11 aa rat D2Dr peptide sequence shows 100% homology with mouse, 90% human and bovine and 72% with dog D2DR receptors. The antibody has been shown to cross react with human (CNS and peripheral), Lobster, squid and crawfish.
USE: Western Blotting (1:500-1:1K of neat sera using Chemiluminescence technique). -must optomize for each application -it may be necessary to load 100-200ug of purified striatal or other tissue membranes to visualize the D2R bands. Reactive with both native and denatured D2R bands.
