Antisense oligonucleotides (ASOs) are widely used for silencing gene expression. The ability to use these synthetic agents to control gene expression is starting to show promising outcomes. With considerable advances in ASO chemical modifications and delivery systems, their potency in vivo has improved. Therefore, more sensitive bioanalytical techniques and better mitigation strategies are required to eliminate interferences in the assay. Hybridization ELISA is an effective and accurate approach to quantify parental ASOs in circulation and in their targeted tissue. Join us as we review case studies highlighting the scientific considerations and regulatory challenges of hybridization ELISA.

What will you learn?

  • The advantages and limitations of hybridization ELISA
  • The different types of hybridization ELISAs and how to choose the right format
  • The possible platforms to use for hybridization ELISA
  • The common bioanalytical issues encountered and mitigation plans
  • The most common challenges encountered with different matrices and tissues

Who may this interest?

  • Bioanalytical scientists
