Gelatin Coating: Collagen is a water-soluble protein polymer obtained through the hydrolysis of collagen. Gelatin coating promotes the attachment and growth of various cell types and can be used for culturing normal or transfected cells, such as vascular endothelial cells, cardiomyocytes, embryonic stem cells, and pancreatic islet cells. It facilitates the adhesion of multiple cell types, and pre-coated gelatin layers save time and costs in experimental preparation. Batch-to-batch consistency ensures the reproducibility of experimental results.
