Product Summary This DuoSet ELISA Development kit contains the basic components required for the development of sandwich ELISAs to measure natural and recombinant human Glial Fibrillary Acidic Protein (GFAP). The suggested diluent is suitable for the analysis of most cell culture supernate, serum, and plasma samples. Diluents for complex matrices, such as serum and plasma, should be evaluated prior to use in this DuoSet. Preparation and Storage Shipping | The product is shipped at ambient temperature. Upon receipt, store it immediately at the temperature recommended below. | Storage | Store the unopened product at 2 - 8 °C. Do not use past expiration date. |
Background: GFAPGlial Fibrillary Acidic Protein (GFAP) is a type III intermediate filament protein. GFAP is the predominant component of astrocyte intermediate filaments in the central nervous system and is often used as an astrocytic marker. It has also been detected in the glial cells of the enteric nervous system and some Schwann cells in the peripheral nervous system. Long Name: | Glial Fibrillary Acidic Protein | Entrez Gene IDs: | 2670 (Human); 14580 (Mouse); 24387 (Rat) | Alternate Names: | ALXDRD; FLJ45472; GFAP astrocytes; GFAP; glial fibrillary acidic protein |
Assay Procedure Refer to the product datasheet for the complete assay procedure. Bring all reagents and samples to room temperature before use. It is recommended that all samples, standards, and controls be assayed in duplicate. 1. Prepare all reagents, standard dilutions, and samples as directed in the product insert. 2. Remove excess microplate strips from the plate frame, return them to the foil pouch containing the desiccant pack, and reseal. 3. Add 50 μL of Assay Diluent to each well. 4. Add 50 μL of Standard, control, or sample to each well. Cover with a plate sealer, and incubate at room temperature for 2 hours. 5. Aspirate each well and wash, repeating the process 4 times for a total of 5 washes. 6. Add 100 μL of Conjugate to each well. Cover with a new plate sealer, and incubate at room temperature for 2 hours. 7. Aspirate and wash 5 times. 8. Add 100 μL Substrate Solution to each well. 9. Add 100 μL of Stop Solution to each well. Read at 450 nm within 30 minutes. Set wavelength correction to 540 nm or 570 nm. |
