| UniProt Protein Function: | PPY: Pancreatic hormone is synthesized in pancreatic islets of Langerhans and acts as a regulator of pancreatic and gastrointestinal functions. Belongs to the NPY family. |
| UniProt Protein Details: | Protein type:Secreted; Secreted, signal peptide Chromosomal Location of Human Ortholog: 17q21 Cellular Component: cytoplasm; extracellular region; extracellular space Molecular Function:G-protein-coupled receptor binding; hormone activity; neuropeptide hormone activity; receptor binding Biological Process: cell-cell signaling; digestion; feeding behavior; neuropeptide signaling pathway; positive regulation of defense response to virus by host; protein secretion; regulation of appetite |
| NCBI Summary: | This gene encodes a member of the neuropeptide Y (NPY) family of peptides. The encoded 95 aa preproprotein is synthesized in the pancreatic islets of Langerhans and proteolytically processed to generate two peptide products. These products include the active pancreatic hormone of 36 aa and an icosapeptide of unknown function. This hormone acts as a regulator of pancreatic and gastrointestinal functions and may be important in the regulation of food intake. Plasma level of this hormone has been shown to be reduced in conditions associated with increased food intake and elevated in anorexia nervosa. In addition, infusion of this hormone in obese rodents has shown to decrease weight gain. Alternative splicing results in multiple transcript variants, at least one of which encodes an isoform that is proteolytically processed. [provided by RefSeq, Jan 2016] |

*ノート: プロトコルは、各バッチ/ロットに固有です。正しい手順については、キットに含まれているプロトコルに従ってください。
使用前に、TMB基質を37°Cで少なくとも30分間平衡化します。サンプルと試薬を希釈するときは、完全に均一に混合する必要があります。各テストの標準曲線をプロットすることをお勧めします。
| ステップ | プロトコル |
| 1. | Set standard, test sample and control (zero) wells on the pre-coatedplate respectively, and then, record their positions. It isrecommended to measure each standard and sample in duplicate. Washplate 2 times before adding standard, sample and control (zero) wells! |
| 2. | Add Sample and Biotin-detection antibody: Add 50µL of Standard, Blank or Sample per well. The blankwell is added with Sample Dilution Buffer. Immediately add 50 µL of biotin-labelled antibody workingsolution to each well. Cover with the plate sealer provided. Gently tap the plate to ensure thoroughmixing. Incubate for 45 minutes at 37°C. (Solutions are added to the bottom of micro-ELISA platewell, avoid touching plate walls and foaming). |
| 3. | Wash: Aspirate each well and wash, repeating the process three timesWash by filling each well with Wash Buffer (approximately 350µL)using a squirt bottle, multi-channel pipette, manifold dispenser orautomated washer. Complete removal of liquid at each step is essentialto good performance. After the last wash, remove any remaining WashBuffer by aspirating or decanting. Invert the plate and pat it againstthick clean absorbent paper. |
| 4. | HRP-Streptavidin Conjugate(SABC): Add 100µL of SABC workingsolution to each well. Cover with a new Plate sealer. Incubate for30minutes at 37°C. |
| 5. | Wash: Repeat the aspiration/wash process for five times. |
| 6. | TMB Substrate: Add 90µL of TMB Substrate to each well. Coverwith a new Plate sealer. Incubate for about 10-20 minutes at 37°C.Protect from light. The reaction time can be shortened or extendedaccording to the actual color change, but not more than 30minutes.When apparent gradient appeared in standard wells, you can terminatethe reaction. |
| 7. | Stop: Add 50µL of Stop Solution to each well. Color turn toyellow immediately. The adding order of stop solution should be as thesame as the substrate solution. |
| 8. | OD Measurement: Determine the optical density (OD Value) of each wellat once, using a microplate reader set to 450 nm. You should open themicroplate reader ahead, preheat the instrument, and set the testing parameters. |
ELISAアッセイを実施する場合、可能な限り最良の結果を達成するためにサンプルを準備することが重要です。以下に、さまざまなサンプルタイプのサンプルを準備するための手順のリストを示します。
| サンプルタイプ | プロトコル |
| 血清 | If using serum separator tubes, allow samples to clot for 30 minutes at room temperature. Centrifuge for 10 minutes at 1,000x g. Collect the serum fraction and assay promptly or aliquot and store the samples at -80°C. Avoid multiple freeze-thaw cycles. If serum separator tubes are not being used, allow samples to clot overnight at 2-8°C. Centrifuge for 10 minutes at 1,000x g. Remove serum and assay promptly or aliquot and store the samples at -80°C. Avoid multiple freeze-thaw cycles. |
| プラズマ | Collect plasma using EDTA or heparin as an anticoagulant. Centrifuge samples at 4°C for 15 mins at 1000 × g within 30 mins of collection. Collect the plasma fraction and assay promptly or aliquot and store the samples at -80°C. Avoid multiple freeze-thaw cycles. Note: Over haemolysed samples are not suitable for use with this kit. |
| 尿および脳脊髄液 | Collect the urine (mid-stream) in a sterile container, centrifuge for 20 mins at 2000-3000 rpm. Remove supernatant and assay immediately. If any precipitation is detected, repeat the centrifugation step. A similar protocol can be used for cerebrospinal fluid. |
| 細胞培養上清 | Collect the cell culture media by pipette, followed by centrifugation at 4°C for 20 mins at 1500 rpm. Collect the clear supernatant and assay immediately. |
| 細胞溶解物 | Solubilize cells in lysis buffer and allow to sit on ice for 30 minutes. Centrifuge tubes at 14,000 x g for 5 minutes to remove insoluble material. Aliquot the supernatant into a new tube and discard the remaining whole cell extract. Quantify total protein concentration using a total protein assay. Assay immediately or aliquot and store at ≤ -20 °C. |
| 組織ホモジネート | The preparation of tissue homogenates will vary depending upon tissue type. Rinse tissue with 1X PBS to remove excess blood & homogenize in 20ml of 1X PBS (including protease inhibitors) and store overnight at ≤ -20°C. Two freeze-thaw cycles are required to break the cell membranes. To further disrupt the cell membranes you can sonicate the samples. Centrifuge homogenates for 5 mins at 5000xg. Remove the supernatant and assay immediately or aliquot and store at -20°C or -80°C. |
| 組織溶解物 | Rinse tissue with PBS, cut into 1-2 mm pieces, and homogenize with a tissue homogenizer in PBS. Add an equal volume of RIPA buffer containing protease inhibitors and lyse tissues at room temperature for 30 minutes with gentle agitation. Centrifuge to remove debris. Quantify total protein concentration using a total protein assay. Assay immediately or aliquot and store at ≤ -20 °C. |
| 母乳 | Collect milk samples and centrifuge at 10,000 x g for 60 min at 4°C. Aliquot the supernatant and assay. For long term use, store samples at -80°C. Minimize freeze/thaw cycles. |
