Why In Vitro Biological Testing Matters
In vitro biological testing bridges the gap between the lab and the mammalian cells by showing exactly how liposomes interact with live cells. By mimicking real physiological conditions, these studies provide crucial data on cellular safety, intracellular absorption, and molecular efficacy. This essential screening serves as a strategic roadmap, providing clear guidelines to determine whether a product is fully optimised and ready to advance to further in vivo studies and subsequent human consumption.
In vitro cytotoxicity & Biocompatibility
-
Cell viability Study (MTT)
Evaluation of cell viability in standard cell lines (L929, CHO, HepG2) as per ISO 10993-5, when exposed to liposomal API
-
Cell Proliferation & Migration Study
Correlating colony-formation (proliferation) and wound-healing assays (migration) to validate cytotoxicity and cell recovery behaviour.
-
Hemocompatibility Assay:
Evaluation using fresh human blood to determine RBC compatibility, with ≤ 5% hemolysis considered acceptable.
-
Osmotic Fragility Analysis:
This study measures the structural resistance of red blood cells to hemolytic shock (bursting) when exposed to varying osmotic stresses in the presence of our liposomes.
In Vitro Efficacy & Mechanistic Insights
-
Cellular Uptake Study
Assessment of liposomal transport and absorption across intestinal cell models (Caco-2).
-
Fluorescence-Based Tracking
