Geltrex LDEV-free stem cell-qualified reduced-growth factor basement membrane matrix is a soluble form of basement membrane extracted from murine Engelbreth-Holm-Swarm (EHS) tumors and is free of viruses, including lactose dehydrogenase elevating virus (LDEV) sometimes found in this type of preparation. Routinely used for attachment and maintenance of human iPSCs or embryonic stem cells, every lot of this matrix is quality control tested using hESCs or iPSCs to help ensure growth and pluripotency of each lot.

Features of Geltrex Reduced-Growth Factor Basement-Membrane Matrix, LDEV-free, stem cell-qualified, include:

Every lot qualified using hESC or iPSC, helping reduce the need for customers to lot screen

Free of lactose dehydrogenase elevating virus (LDEV), making it safe for all types of cell culture

Consistent protein concentration lot-to-lot, helping ensure reproducible results

Gain reliability and consistency in your hESC/iPSC studies

Human hESCs/iPSCs have specific needs for attachment and maintenance and some lots of basement membrane extract may not provide adequate support. Geltrex Reduced-Growth Factor Basement-Membrane Matrix, LDEV-free, stem cell-qualified, has been tested for support of hESC/iPSC growth and pluripotency, minimizing the need to test multiple lots to find one that works. Our consistent manufacturing process helps ensure a protein concentration with very little variation from lot-to-lot, so you can have confidence in every purchase.

Free of LDEV contamination

Recent advances in processing of EHS tumor cells have resulted in virus-free basement membrane extracts. Every lot is tested by tested by RT-PCR methods so you can be confident that every lot is virus-free.
