Applications: Use as a positive control for transductionOptimize transduction assays and track protein expression over time
Description: Adeno-Associated Virus Serotype 4 (AAV4) contains an expanded p5 promoter region compared to either AAV2 or AAV3. The AAV4 Rep gene product shows greater than 90% homology with the Rep products of AAV2 and AAV3. AAV4 can transduce human, monkey, and rat cells, and efficiently transduces type B astrocytes in the subventricular zone and glia overlying the rostral migratory stream neural tube.These AAV particles constitutively express ZsGreen under a CMV promoter. ZsGreen is a human codon-optimized variant of the green fluorescent protein isolated from reef coral (Zoanthus sp). It has been engineered for higher expression in mammalian cells and is up to four times brighter than enhanced GFP (eGFP). ZsGreen expression and AAV transduction efficiency can easily be verified and optimized by fluorescence microscopy or flow cytometry. ZsGreen has an excitation wavelength of 493 nm and an emission wavelength of 505 nm.
Formulation: AAV was produced in HEK293-AAV cells and is supplied in PBS-MK (PBS Magnesium-Potassium) buffer containing 0.01% Pluronic F68.
Purification: The purity of the AAV4 particles was confirmed to be greater than 90% by staining with One-Step Lumitein™ UV Protein Gel Stain (Biotium #21005-1L). Purity will vary with each lot; the exact value will be provided with each shipment.
Storage Stability: AAV is shipped with dry ice. For long-term storage, it is recommended to store AAV at -80°C.
Supplied As: Two vials (50 µl x 2) of AAV at a titer ≥1 x 1012 TU/ml. The titer is determined by qPCR and will vary with each lot; the exact value will be provided with each shipment.
Warnings: Avoid freeze/thaw cycles
Biosafety Level: BSL-1
