Produktbeschreibung

Control peptide for G1015-44 (antiserum) and G1015-44A (affinity purified antibody). Synthetic peptide consisting of 16aa sequence near the N-terminus of rat GBR1b. Peptide sequence is 100% conserved in various alternatively spliced rat GBR1b (844aa), GBR1c (875aa) and GBR1d (812aa). No significant sequence homology is detected with GBR1a or GBR2 or other GABA receptors. GABA (g-amino butyric acid) is the most abundant neurotransmitter in mammalian brain. GABA exerts its effects through ionotropic ligand-gated GABAA, GABAC and GABAB receptors (GABABRs). Presynaptic GABABRs inhibit neurotransmitter release by down regulating high voltage activated Ca+2 channels, whereas postsynaptic GABABRs decrease neuronal excitability by activating a prominent inwardly rectifying K+ (Kir) conductance that underlies the late inhibitory postsynaptic potential. Two N-terminal splice variants GABABR1 (also called GBR1), GABABR1a (GBR1a, rat 960aa, apparent mol wt ~130kD, human 961aa) and GABABR1b (GBR1b, rat 844aa, apparent MW 100kD, human 844aa) have been cloned and characterized. GABABRs are characterized by the presence of a cleavable signal peptide, a large extracellular N-terminus, 7 TM domains, and C-terminal, cytoplasmic domain. GABABRs are expressed in all major areas of the brain. Recently GABABR2 (or GBR2) has been cloned from rat (940aa) and human (941aa). GBR2 forms heterodimer with GBR1 through interaction at the intracellular C-terminal regions. Heterodimerization appears to be important in transporting GBR1 to the membrane and expression of functional receptors. GBR2 also colocalized with GBR1. Applications: Suitable for use in ELISA and Antibody Blocking. Not suitable for use in Western Blot due to low molecular weight. Other applications have not been tested. Recommended Dilution: Antibody Blocking: 5-10ug per 1ul G1015-44 (antiserum) or 1ug G1015-44A (affinity purified antibody). ELISA: 0.5-1ug/ml. Control peptide can be used to coat ELISA plates at 1ug/ml. Optimal dilutions to be determined by the researcher. Storage and Stability: May be stored at 4C for short-term only. For long-term storage, store at -20C. Aliquots are stable for at least 6 months at -20C. For maximum recovery of product, centrifuge the original vial after thawing and prior to removing the cap. Further dilutions can be made in assay buffer.
