Assay Working Ranges
Part No. VHH Affinity Ligand standard Typical assay working ranges (pg/mL)
Z03793 AAVX Affinity Ligand Standard 10-640
Z03794 AVB Affinity Ligand Standard 312.5-20,000
Z03795 AAV8 Affinity Ligand Standard 40-2,560
Z03796 KappaXP Affinity Ligand Standard 31.25-2,000
The kit includes the CaptureSelect™ (a trademark of Thermo Fisher Scientific) AAVX Affinity Ligand standard (a VHH affinity ligand), and the assay can be expanded by adding alternative standards, such as CaptureSelect™ AAV8 Affinity Ligand Standard, CaptureSelect™ KappaXP Affinity Ligand Standard, and Capto AVB Affinity Ligand Standard. The kit can also be used for a variety of other VHH affinity ligand residual assays or VHH drug quantification. Users can follow the protocol of the kit to evaluate the suitability of the test for other VHH.

Assay Principle VHH Affinity Ligand ELISA Kit is based on the sandwich ELISA method. When standards or samples are added to the capture plate coated with the anti-VHH capture antibody, the VHH Affinity Ligand in the standards or samples can be captured on the plate. Then anti-VHH detection antibody conjugated with biotin is added to interact with the VHH Affinity Ligand bound on the plate. Streptavidin-Horseradish Peroxidase conjugate (Streptavidin-HRP) is added to interact with the biotin conjugated anti-VHH antibody (Biotin Anti-VHH Antibody). After washing steps, 3,3',5,5'-Tetramethylbenzidine solution (TMB Solution) is added to the plate and color development is stopped by addition of stop solution. Application of the Stop Solution results in the color changing from blue to yellow. The color intensity can be read at 450 nm by a microplate reader. The VHH standard curve can be used to accurately quantify the amount of VHH in the samples.
