Anti-Dopamine D2 Receptor Antibody, cytoplasmic domain, long form

Specific for Dopamine Receptor D2 long form. Dopamine D2 receptor is known to exist in the short (D2S) and the long (D2L) forms that are encoded by splice variants of a single gene and differ only by the presence of an additional 29 amino acid in the intracellular, cytoplasmic loop 3 (Dal Toso et al. 1989; Grandy et al. 1989; Monsma et al. 1990; Giros et al. 1989). D2L receptor is a 446 aa, G-protein coupled and transmembrane receptor protein (Boundy et al. 1993) The 27 aa rat D2RL peptide used for immunization was found only in the D2 long form and there is no significant homology with other dopamine receptors (D1, D2 short, and D3-D5).

SPECIES REACTIVITIES: The immunogen peptide shows sequence homology of 96% with human/bovine (26/27 aa), 62% with Xenopus (17/27 aa) D2L receptors. Antibodies generated to the rat sequence have been shown to recognize the canine D2R (Boundy et al. 1993). Antibody cross-reactivity with various species is not known.

A 27 amino acid peptide sequence from the rat D2 long form within the cytoplasmic loop #3.

Western blot: 1-10 μg/mL (Chemiluminescence technique) The predicted size of D2L form is approximately 50 kDa. However, additional bands at approximately 60 and 100 kDa, and others are typically seen in various tissues (Boundy, et al. 1993; Sakata, et al. 1992; Farooqui et al. 1991, 1992; Brock et al. 1992; Farooqui & Prasad 1992). Approximately 100-400 μg of membrane protein/lane should be loaded to visualize various bands.

Immunohistochemistry: 1-20 μg/mL on paraformaldehyde fixed sections.

Immunoprecipitation: 1-10 μg using 100-400 μg of protein (Boundy, et al. 1993).

ELISA: 0.5-1.0 μg/mL (1 μg/mL immunogen peptide (AG211)/well)

Optimal working dilutions must be determined by the end user.
