The Essential 8™ Adaptation Kit includes Essential 8™ Medium and recombinant human Laminin 521 (rhLaminin-521) for optimal survival during transition from feeder-dependent to feeder-free culture. rhLaminin-521 has been proven to promote cellular survival under stressful conditions in the absence of small molecule inhibitors. In addition, rhLaminin-521 has been shown to support PSC growth for >20 passages without any signs of karyotypic abnormalities and to maintain the ability of PSCs to differentiate into all three germ line lineages. rhLaminin-521 can also be purchased separately.
The Essential 8 Adaptation Kit is: • Robust–transition cells between feeder-dependent and feeder-free culture systems with minimal effort • Physiologically relevant–expand cells with minimal differentiation • Scalable–passage stem cell lines as single cells with no impact to genetic stability
Trouble-free transition When used with Essential 8 Medium, rhLaminin-521 provides a robust culture matrix that supports pluripotent stem cell adherence and expansion during the transition from feeder-dependent culture systems.
Confident expansion rhLaminin-521 is expressed in blastocysts and therefore provides an environment mimicking the human stem cell niche.
Easy scale-up rhLaminin-521 promotes stable pluripotent stem cell maintenance as single cells in the absence of ROCK inhibitors.
For Research Use Only. Not for use in diagnostic procedures.

Frequently asked questions (FAQs)
Can I use the Poly-D-Lysine matrix with other coatings?
iPSC-derived neurons have been cultured successfully on Poly-D-Lysine with a secondary coating of mouse and human laminin.
I am interested in using StemFlex Medium in somatic cell reprogramming. What protocol should I follow for blood cells?
We have evaluated the use of Cytotune-iPS 2.0 Sendai Reprogramming Kit (Cat. No. A16517) for somatic cell reprogramming of CD34+ blood cells. For CD34+ cells, follow the instructions provided in the Cytotune 2.0 reprogramming manual for feeder-free reprogramming (pgs. 39-44). On Day 3, you can utilize rhVTN-N (Cat. No. A14700), Geltrex (Cat. No. A1413302), or rhLaminin-521 (Cat. No. A29248 or A29249). From Day 8 onward, rather than feeding daily with Essential 8 Medium, reprogrammed CD34+ cells should be fed every-other-day with StemFlex Medium.
I am interested in using StemFlex Medium in somatic cell reprogramming. What protocol should I follow for human fibroblasts?
We have evaluated the use of Cytotune-iPS 2.0 Sendai Reprogramming Kit (Cat. No. A16517) for somatic cell reprogramming of both neonatal and adult human dermal fibroblasts. For fibroblasts, follow the instructions provided in the Cytotune 2.0 reprogramming manual for feeder-free reprogramming (pgs. 16-20). On Day 7, you may use rhVTN-N (Cat. No. A14700), Geltrex matrix (Cat. No. A1413302), or rhLaminin-521 (Cat. No. A29248 or A29249). From Day 8 onward, rather than feeding daily with Essential 8 Medium, we recommend that you feed reprogrammed fibroblasts every-other-day with StemFlex Medium.
Can I use Geltrex matrix instead of rhLaminin-521 for clonal expansion workflows where cells are seeded at 1-5 cells per well of a 96-well plate?
We have not yet evaluated the Geltrex matrix system for clonal expansion in the presence of StemFlex Medium. However, rhLaminin-521 does provide optimal survival of cells following single-cell passaging and thus this matrix is recommended for such critical applications.
What protocol is recommended for delivery of Cas9 protein:guide RNA complex to my PSCs cultured in StemFlex Medium?
We recommend use of the Neon Electroporation device for electroporation of PSCs with Cas9 protein:guide RNA complex following the protocol guidance in the following demonstrated protocol (https://www.thermofisher.com/content/dam/LifeTech/Documents/PDFs/PG1584-PJT1313-COL31227-Demonstrated-Protocol-Performing-CRISPR-Cas9-FHR.pdf); see the section entitled Knockout by electroporation of RNP using the Neon Transfection System. We have seen that the Neon electroporation protocols 7 and 14 provide optimal indel formation while maintaining cell survival. However, the electroporation conditions may need to be optimized for your pluripotent cell line.
