商品描述

VitroCol®collagen is the first widely available, naturally produced purified human collagen for research purposes. VitroCol® sets the standard for purity (>99.9% collagen content), functionality and represents the only native-like human collagen offered.

VitroCol® collagen is naturally secreted from human neo-natal fibroblast cells. The human fibroblasts are cultured in optimal conditions allowing the fibroblasts to naturally and efficiently secret extracellular matrix. The extracellular matrix is then processed and purified to yield the naturally produced human collagen.

VitroCol® is approximately 97% Type I human collagen with the remainder being comprised of Type III collagen. It contains high monomer content as measured by gel permeation chromatography.

This product is supplied as a lyophilized powder with 15 mg of human collagen. When reconstituted with 5 ml of sterile 0.01 N HCl, a concentration of approximately 3 mg/ml is achieved.

VitroCol® is especially ideal for human cell culture systems when coating of surfaces and providing preparations of thin layers of culturing cells. VitroCol®, lyophilized form is not recommend for the formation of a solid gel. VitroCol® human collagen is provided in user-friendly packaging for use and storage. VitroCol® is supplied as a sterile, lyophilized powder.

Cell Attachment Bioassay

To demonstrate cell attachment, cells were seeded onto surfaces coated with the matrix product and onto negative control surfaces without the matrix product. Cells were seeded onto surfaces using serum-free DMEM media. All surfaces were blocked with a solution containing 1% BSA. Cells were then allowed to attach for one (1) hour at 37°C. The culture surfaces were washed with DPBS. The results indicate significant cell attachment with surfaces coated using the matrix product.
