AI and GenAI Applications to Help Optimize Purification and Yield of Antibodies From Plasma (October 2024)

Deriving antibodies from plasma involves a multi-step process, from plasma collection to antibody purification and quality control, ensuring the final product is safe and effective for therapeutic, diagnostic, or research use. Krish Gosh, PhD, MBA, President of TCG Digital, joined LCGC International to discuss how AI/GenAI applications can optimize several steps to enhance yield, profitability, and process monitoring.

Chromatography Detects Toxins in Tea Samples
High-performance liquid chromatography-tandem mass spectroscopy (HPLC–MS/MS) chromatography reveals pyrrolizidine alkaloids (PA)/pyrrolizidine alkaloid N-oxides (PANO) toxin risks in 63 tea samples.
Figure 2. Split injection used to measure triplicate test of MTBE, hexane, o-xylene, and 1-methylnaphthalene comparing different solvents (methanol, methylene chloride) and column insertion distances starting with 0.5 mm, 5.0 mm, 10.0 mm, 15 mm, and 20.0 mm. Methanol had the best performance at the 5.0 mm insertion distance and methylene chloride looked slightly better at the 0.5 mm. We would still recommend not going below the 5.0 mm manufacturer recommended insertion distance.
Revisiting insertion distance for methanol and methylene chloride in GC analysis and confirming that insertion depth strongly affects response and reproducibility.
