一般描述

Full-length human GPR73L1 cDNA encoding PK2
Prokineticins, also known as endocrine gland vascular endothelial growth factors (EG-VEGF), are two ~10 kD secreted proteins originally described to mediate angiogenesis and gastrointestinal smooth muscle contraction (Li et al., 2001; LeCouter et al., 2003). Subsequently, prokineticins have been found to mediate central nervous system functions including circadian rhythms and olfactory bulb development (Cheng et al., 2002; Ng et al., 2005). Two Gq-coupled receptors, PK1 and PK2 (also known as GPR73a and GPR73b), mediate cellular responses to prokineticins (Lin et al., 2002). Millipore′s PK2 membrane preparations are crude membrane preparations made from our proprietary stable recombinant cell lines to ensure high-level of GPCR surface expression; thus, they are ideal HTS tools for screening of agonists and antagonists at PK2. The membrane preparations exhibit a Kd of 0.36 nM for [125I]-MIT-1. With 0.3 nM [125I]-MIT-1, 10μg/well PK2 Membrane Prep typically yields greater than 5-fold signal-to-background ratio.

应用

Human PK2 / PKR2 GPCR membrane preparation for Radioligand binding Assays & GTPγS binding.
Radioligand binding assay and GTPγS binding.

生化/生理作用

  • GPCR Class: A
  • Protein Target: PK2/PKR2
  • Target Sub-Family: Prokineticin

产品规格

Membranes are mixed with radioactive ligand and unlabeled competitor (see Figures 1 and 2 for concentrations tested) in binding buffer in a nonbinding 96-well plate, and incubated for 1-2 h.Prior to filtration, an FC 96-well harvest plate (Millipore cat. # MAHF C1H) is coated with 0.33% polyethyleneimine for 30 min, then washed with 50mM HEPES, pH 7.4,0.5% BSA.Binding reaction is transferred to the filter plate, and washed 3 times (1 mL per well per wash) with Wash Buffer.The plate is dried and counted.

Binding buffer: 50 mM Hepes, pH 7.4, 5 mM MgCl2, 1 mM CaCl2, 0.2% BSA, filtered and stored at 4℃.

Radioligand: [125I] MIT-1 (Perkin Elmer#: NEX-410)

Wash Buffer: 50 mM Hepes, pH 7.4, 500mM NaCl , 0.1% BSA, filtered and stored at 4℃.

外形

One package contains enough membranes for at least 200 assays (units), where a unit is the amount of membrane that will yield greater than 5-fold signal:background with 125I-labeled MIT-1 at 0.3 nM

Liquid in packaging buffer: 50 m

储存及稳定性

Maintain frozen at -70℃ for up to 2 years. Do not freeze and thaw.
