NutriCoat™ Attachment Solution


Cost-effective, efficient, standardized supplement designed for the attachment of human mesenchymal stem cells under serum-free and xeno-free culture condition.

Vitronectin ACF
Item no.


Recombinant lyophilized protein for the attachment of human pluripotent stem cells.

LaminStem™ 521
Item no.


A chemically defined, animal component-free matrix for feeder-free culture of human embryonic stem (hES) cells and induced pluripotent stem (hiPS) cells. LaminStem 521 facilitates self-renewal of both hES cells and iPS cells in a chemically defined, feeder-free and xeno-free cell culture system. When used with NutriStem® hPSC XF Medium, LaminStem 521 has been proven to promote cellular survival and expansion of hES and hiPS cells after plating from single cell suspension.

A wide range of matrices, substrates, and attachment solutions, from solutions derived from bovine and human to chemically-defined, animal-component free solutions. All are manufactured in a state-of-the-art, cGMP-compliant manufacturing plant.

Sartorius' matrices and attachment solutions are specially designed laminin, vitronectin, fibrinogen, and fibronectin based solutions. They are validated and quality tested to provide optimal attachment and growth of animal cells, including mesenchymal stromal cells (MSCs) and pluripotent stem cells (ESCs and iPSCs).
