ELN 441958是一种B1受体拮抗剂,能够抑制B1激动剂配体[3H] DAKD与IMR-90细胞结合(Ki:0.26 nM),相较于B2受体,它对B1受体的抑制作用具有更高的选择性,且比抑制μ阿片受体选择性高500多倍,比抑制δ阿片受体选择性高2000多倍。
产品描述
ELN-441958 is a potent, neutral antagonist of B1 receptor, inhibits the binding of the B1 agonist ligand [3H]DAKD to IMR-90 cells with Ki of 0.26 nM. ELN-441958 is highly selective for B1 over B2 receptors.
激酶实验
IGF-IR Peptide Autophosphorylation: One microgram of constitutively active IGF-IR kinase domain peptide isincubated +/? varying concentrations of PQ 401 in 2% DMSO in 40 mM Tris (pH 7.4), 80 μMEGTA, 0.25% 2-mercaptoethanol, 80 μM Na3VO4, 10 mM MgCl2, and 2 mM MnCl2 for 20 minutes. ATP isthen added at a final concentration of 20 μM. Autophosphorylation of the kinase domain peptide isallowed to occur for 20 minutes at 22℃. The reaction isstopped by the addition of SDS-reducing buffer and the samples are run on SDS-PAGE. Following transfer to nitrocellulose membrane, peptide autophosphorylation isdetermined by Western blotting employing an antibody against phosphotyrosine (PY20).
