Product Summary The Quantikine Human XCL1/Lymphotactin Immunoassay is a 4.5 hour solid-phase ELISA designed to measure human Lymphotactin in cell culture supernates, serum, and plasma. It contains E. coli-expressed recombinant human Lymphotactin and has been shown to accurately quantitate the recombinant factor. Results obtained using natural human Lymphotactin showed linear curves that were parallel to the standard curves obtained using the Quantikine kit standards. These results indicate that this kit can be used to determine relative mass values for naturally occurring human Lymphotactin.

Background: XCL1/LymphotactinLymphotactin (Lptn), also known as SCM-1a and ATAC, belongs to the C or gamma subfamily of chemokines and has been designated XCL1. Human Lymphotactin encodes a 114 amino acid (aa) precursor with a 21 aa predicted signal peptide. The gene for lymphotactin has been mapped to chromosome 1 in both human and mouse.

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. |
