Revvity, 64AAV2PEH, HTRF AAV2 Detection Kit, 10,000 Assay Points

Overview
Adeno-associated virus (AA) vectors are the leading platform for gene delivery for the treatment of a variety of human diseases. AAV Serotype 2 (AAV2) was one of the first AAV serotypes studied and used as vectors for specific and natural tropism towards targeted cell types such as neurons and hepatocytes or tissues such as skeletal muscles and the retina. The AAV2 kit is designed to detect and quantify AAV2 particles in an easy-to-use, no-wash format. The simple and robust procedure benefits from increased throughput compared to ELISA.
HTRF assays offer many advantages over other technologies:

Homogeneous add-and-read format
No wash steps
Low background
Straightforward miniaturization from 96- or 384-well microplates to high density assay formats such as 384-well low volume and 1536-well plates
Stable signal, providing flexibility in time of readout or size of assays
How it works
AAV2 capsid assay principle
The Adeno-Associated Virus serotype 1 (AAV2) assay measures AAV2 Capsid in cell supernatant or cell lysate. The assay uses two anti-AAV2 antibodies: one coupled to HRP, that binds to anti-HRP d2 (acceptor) in premix 1, and the other coupled to biotin, that binds to Streptavidin Eu-cryptate (donor) in premix 2. In presence of AAV2 Capsid in a cell extract or supernatant, the addition of these conjugates brings the donor fluorophore into close proximity with the acceptor, and thereby generates a FRET signal. Its intensity is directly proportional to the concentration of the capsid present in the sample and provides a means of assessing any changes caused by experimental variability under a no-wash assay format.

 

AAV2 Capsid assay protocol
The AAV2 Capsid assay protocol using a 384-well small volume white plate is described on the right. 5 µL of sample or standard and 5 µL of diluent are dispensed directly into the plate for detection by HTRF® reagents. The Biotin anti-AAV2 antibody is pre-mixed with Streptavidin labeled with the donor, and HRP anti-AAV2 antibody is pre-mixed with anti-HRP labeled with the acceptor. 5 µL of each premix were added. The assay can be run in up to a 1536-well format by simply resizing each addition volume proportionally. Application-Bioprocessing
