Neuromics' ISOKine bFGF in 3-D Cultures

Works Well in Perfusion Models

Our ISOKine^TM FGF is produced in the endosperm tissue of barley grain (Hordeum vulgare), that exhibits up to 50 times less protease activity than E.coli or mammalian cells. Barley seed is void of any human or animal viral contaminants that could jeopardize your cell culture.

It is a proven solution for all cell cultures and starts at the low price of  65 USD/10 ug.

Here's a reference of its use in 3-D Cultures: Tom Kamperman, Sieger Henke, Claas Willem Visser, Marcel Karperien, Jeroen Leijten. Centering Single Cells in Microgels via Delayed Crosslinking Supports Long-Term 3D Culture by Preventing Cell Escape. DOI: 10.1002/smll.201603711.

Figure: Delayed on-chip crosslinking enables centering of single cells in microgels. a) Fluorescence confocal imaging confirmed that delayed enzymatic crosslinking enabled centering of single MSCs in Dex-TA microgels. b) On average, cell-laden microgels were only 9 µm larger than the encapsulated MSCs, effectively resulting in 3D hydrogel coatings of less than 5 µm. c) A standard microfluidic droplet generator was connected to the H2O2 diffusion-based crosslinking chip. The position of cells (white arrows) in non-crosslinking microgel precursor droplets was analyzed d) immediately after droplet generation (t1), at the start of the crosslinking chip (t2), and e) at the end of the crosslinking chip (t3). f) Cell positions within microgels produced using conventional microfluidic encapsulation systems (i.e., with coupled emulsification and gelation) are indicated with gray (i.e., references) and red (i.e., this work) data points. Cell positions within gel precursor droplets along the modular microfluidic setup are indicated with blue data points. Cell positions within delayed enzymatically crosslinked microgels are indicated with green data points. g) Cell position analyses of various combinations of distinct hydrogel materials (i.e., Dex-TA, Dex-HA-TA, PEGDA), cell types (i.e., MIN6, MSC), and crosslinking methods (i.e., enzyme-based and photo-crosslinking), revealed that delayed crosslinking consistently resulted in significantly increased cell-centering as compared to the conventional encapsulation approach where emulsification and gelation are coupled.
