Product Description |
GenScript AAV2 Titer
Capsid ELISA Kit (Cat. No. L00942) is a Sandwich ELISA Kit that is designed for
quantitatively measuring the total capsid titer of adeno-associated virus
serotype 2 (AAV2) in testing samples during viral vector production. The total
capsid titer stands for the amount of all fully assembled viral capsids,
including full and empty AAV2 capsids. This ELISA kit provides an easy,
accurate, and reproducible method for AAV2 titration. Adeno-associated
viruses (AAV) are now widely-used viral vectors for gene therapy, with AAV2 being
the most extensively studied serotype. When using AAV2 as the viral vector in gene
therapy, determination of the total capsid titer of the purified AAV2 particle
product is an essential characterization procedure, and represents a critical
step in clinical applications. |

Assay Principle |
AAV2 Titer Capsid ELISA Kit is based on the sandwich ELISA method. When standards (AAV2 Control) or samples are added to the capture plate, the AAV2 capsids in the sample can be captured on the plate coated with the capture antibody. Then the detection antibody (Biotin Anti-AAV2 Antibody) conjugated with biotin is added to interact with the AAV2 capsids bound on the plate. Streptavidin-Horseradish Peroxidase conjugate (Streptavidin-HRP) is added to interact with the biotin conjugated detection antibody. After washing steps, 3,3',5,5'-Tetramethylbenzidine solution (TMB Solution) is added resulting in formation of blue color. The reaction is stopped by adding Stop Solution. Application of the Stop Solution results in the color changing from blue to yellow. The intensity of the color can be read at 450 nm and 650 nm by a microplate reader. The quantity of AAV2 capsids in the sample is precisely quantified against an AAV2 standard curve.
