Area of Science:

  • Molecular Biology
  • Virology
  • Biotechnology

Context:

  • Recombinant adenovirus vectors are crucial for gene therapy and vaccine development.
  • Interleukin-2 (IL-2) plays a vital role in immune responses.
  • Ensuring the quality of recombinant viral vectors is paramount for safety and efficacy.

Purpose:

  • To investigate and optimize quality control methods for recombinant adenovirus-IL2 (Adv-IL2).
  • To establish robust quality specifications for Adv-IL2.
  • To validate the suitability of Adv-IL2 for biological product applications.

Summary:

  • Adv-IL2 was produced with a high titer (3 x 10^10 pfu/mL).
  • Expressed IL-2 levels and bioactivity were quantified (25 ng/mL and 700 U/mL).
  • Purity exceeded 98% by IE-HPLC, with confirmed genomic integrity and absence of adventitious agents via PCR.
