OPN4 Human Recombinant Protein, Synthetic Nanodisc
Specifications
| Product Data | |
| Species | Human |
|---|---|
| Expression Host | HEK293 |
| Tag | C-Flag & Strep Tag |
| Predicted MW | 52.6 kDa |
| Concentration | Please refer to the Certificate of Analysis (COA) for the lot-specific concentration before lyophilization. |
| Buffer | Lyophilized from nanodisc solubilization buffer (20 mM Tris-HCl, 150 mM NaCl, pH 8.0). Normally 5% - 8% trehalose is added as protectants before lyophilization. Do not use solvents with pH lower than 6.5 in subsequent experiments. |
| Reconstitution Method | 1. Before opening the tube cap, centrifuge the sample tube at 5000g for 3-5min at room temperature to ensure the lyophilized sample settles down at the bottom of the tube. 2. Calculate the volume for reconstitution (in µL) using the formula: Quantity (mg)/Concentration (mg/mL)x1000 3. Dissolve the lyophilized protein sample in sterile water based on the calculated volume (µL) 4. After adding sterile water, cover the lid and mix by gently tapping the tube 5-10 times. Note: Do not vortex or vigorously pipette the sample. |
| Storage | Store at -20°C to -80°C for 12 months in lyophilized form. |
| Stability | After reconstitution, if not intended for use within a month, aliquot and store at -80°C . Avoid repeated freezing and thawing. |

| Summary | Opsins are members of the guanine nucleotide-binding protein (G protein)-coupled receptor superfamily. This gene encodes a photoreceptive opsin protein that is expressed within the ganglion and amacrine cell layers of the retina. In mouse, retinal ganglion cell axons expressing this gene projected to the suprachiasmatic nucleus and other brain nuclei involved in circadian photoentrainment. In mouse, this protein is coupled to a transient receptor potential (TRP) ion channel through a G protein signaling pathway and produces a physiologic light response via membrane depolarization and increased intracellular calcium. The protein functions as a sensory photopigment and may also have photoisomerase activity. Experiments with knockout mice indicate that this gene attenuates, but does not abolish, photoentrainment. Alternative splicing results in multiple transcript variants encoding different isoforms. provided by RefSeq, Jul 2008 |
