Human ADAMTS13 Quantikine ELISA Kit Summary

Product Summary

The Quantikine Human ADAMTS13 Immunoassay is a 4.5 hour solid-phase ELISA designed to measure human ADAMTS13 in cell culture supernates, serum, and plasma. It contains CHO cell-expressed recombinant human ADAMTS13 and has been shown to accurately quantitate the recombinant factor. Results obtained using natural human ADAMTS13 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 ADAMTS13.

Preparation and Storage

Background: ADAMTS13

Members of the ADAMTS family contain pro, catalytic, disintegrin-like, cysteine-rich, spacer and a variable number of TS type 1 motifs. In contrast to membrane-anchored ADAMs, ADAMTSs are secreted and are all active proteases. They are essential for aggrecan turnover and procollagen processing, regulation of which is important in many physiological and pathological processes such as angiogenesis and arthritis.

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.
