Case Study
mRNA purity –AUC effectively distinguishes the different components in an mRNA sample, such as truncated mRNA (Peak 1), monomeric mRNA (Peak 2), long-chain mRNA, and mRNA aggregates (Peak 3& 4).

An AAV variant from our library screening showed that the virus was able to package a 6.1kb genome.

AAV variants enriched in different tissues during library screening. AAV libraries were prepared and injected into the hosts. After two weeks, tissues were harvested and viral genomes were isolated for PacBio sequencing. Viral genomes were clustered against different tissues.

CAR expression with escalated MOI using PTLV-SMART platform. Activated T cells transduced with escalated MOI, and FACS employed to demonstrate CAR expression post-7 days culture in G-Rex.
Figure 1
Time course of CAR transduction rates of CD3 T cells and cell viability during manufacturing in two cases. T-cells transduced with lentivirus analyzed by flow cytometry to detect CAR-positive or Protein L-positive cell ratio. T-cells expressed CAR stably in the period of CAR-T cell growth with high cell viability.
