Description
PRINCIPLE OF THE ASSAY This assay employs the quantitative competitive enzyme immunoassay technique. Recombinant Human TACSTD2 antigen has been pre-coated onto a microplate. Standards or samples are premixed with biotin-labeled antibody and then pipetted into the wells. Sacituzumab in the sample competitively binds to the pre-coated protein with biotin-labeled Sacituzumab. After washing away any unbound substances, Streptavidin-HRP is added to the wells. Following a wash to remove any unbound enzyme reagent, a substrate solution is added to the wells and color develops in inversely proportion to the amount of Sacituzumab bound in the initial step. The color development is stopped and the intensity of the color is measured.
Applications
Used for the quantitative determination of Sacituzumab concentration in serum, plasma and cell culture supernatant.
Detection method
Colorimetric
Sample type
Plasma, Serum
Assay type
Quantitative
Range
78.13 - 5,000 ng/mL
Sensitivity
40.3 ng/mL
Precision
Intra-Assay Precision (Precision within an assay): <20%
Three samples of known concentration were tested sixteen times on one plate to assess intra-assay precision.
Inter-Assay Precision (Precision between assays): <20%
Three samples of known concentration were tested in twenty four separate assays to assess inter-assay precision.
Recovery
80-120%
Shipping
2-8 ℃
Stability and Storage
When the kit was stored at the recommended temperature for 6 months, the signal intensity decreased by less than 20%. For unopened kits, if you want to prolong the storage time, please store the Standard, Detection A, Detection B and Microplate at - 20℃, the rest reagents should be store at 4℃.

Background
Sacituzumab govitecan (sacituzumab govitecan-hziy; Trodelvy™) is a Trop-2-directed antibody conjugated to a topoisomerase I inhibitor (SN-38) that is being developed by Immunomedics for the treatment of solid tumours, including breast cancer. In April 2020, sacituzumab govitecan received accelerated approval in the USA for the treatment of adult patients with metastatic triple-negative breast cancer (mTNBC) who have received at least two prior therapies for metastatic disease. Sacituzumab govitecan is undergoing phase III development for breast cancer in the USA and EU, and phase II development for urothelial cancer. It is also being explored for brain metastases, glioblastoma, endometrial cancer and prostate cancer.
