AAV purification kits

Purification of adeno-associated virus (AAV)

The purity of AAV particles is an important factor for obtaining efficient and stable gene transfer in cultured cells and individual animals. However, many currently available AAV purification approaches, such as cesium chloride density gradient centrifugation and iodixanol ultracentrifugation, are time-consuming and require specialized equipment.

Our AAVpro Purification Kit Midi and Maxi (All Serotypes) (Cat. # 6675 and 6666, respectively) can be used to easily purify AAV particles from AAV-producing cell lysates through a simple precipitation and filtration protocol in about four hours.

Alternatively, AAVpro Cell & Sup. Purification Kit Maxi (All Serotypes) (Cat. # 6676) allows the researcher to purify virus particles from both AAV-producing cell lysates and culture supernatant in about seven hours. This provides higher virus yields, especially for serotypes that localize predominantly in supernatants or in both cell lysates and supernatants.

For the number of culture vessels per purification, please see the table below.

Overview

  • Simple workflow: optimized protocol that eliminates the need for freeze-thaw cycles and ultracentrifugation steps
  • High purity for reliable data: purified AAV is suitable for both in vitro and in vivo research
  • Serotype agnostic: precipitation and filtration protocol that can purify AAV particles from any serotype

Please note that the purification method largely depends on the serotype, as different capsid types behave differently within producer cells. This affects where the virus accumulates and how it can be most effectively recovered. See the table below for examples of cellular localization of typical serotypes.

AAV serotype Predominant location Key factor
AAV1 Supernatant Released efficiently into the culture medium
AAV2 Cell pellet Strong affinity for heparin sulfate causes retention within the cells, requiring cell lysis for harvest
AAV3 Cell pellet A low percentage of viral particles is found in the supernatant
AAV4 Cell pellet Only about 8% of particles are found in the supernatant
AAV5 Supernatant More readily released into the culture medium compared to AAV2
AAV6 Cell pellet Primarily associated with cells, though some release occurs
AAV8 Supernatant Found in abundance in and can be efficiently harvested from the culture medium
AAV9 Supernatant Similar to AAV8, it is largely released into the supernatant
