SoloHill® Microcarriers - Animal Protein Coated

Animal Protein Coated Microcarriers

Anchorage dependent cell lines rely heavily on optimal substrate conditions. Collagen has been shown to be an effective promoter of cell attachment and growth in monolayer cultures. With collagen coated microcarriers, processes can be transferred directly out of collagen based monolayers and moved into space efficient 3D cultures with minimal development time. This upgrade allows improved process control and process economics.

Key Features and Benefits

  • Excellent attachment and growth across multiple cell lines
  • No hydration needed, simply sterilize and use.
  • Solid core design able to withstand mechanical harvest methods
  • Starter Kits available to test in your process

The flexibility of this family of microcarriers ensures that millions of grams of SoloHill collagen coated microcarriers are used annually for the production of biopharmaceutical products and animal vaccines. Two features contribute to this success: a micro layer of denatured collagen and a crosslinked polystyrene core. Despite the small amount of animal protein used, SoloHill collagen microcarriers demonstrate ideal attachment kinetics across a wide variety of tested cell lines. The solid core design ensures no carrier fragmentation during culture conditions or aggressive harvest protocols. The smooth surface prevents absorption of media components and ensures quick proteolysis for faster preparation of single cell suspensions. Viable cell yield typically exceeds 95% and cells perform well in subsequent inoculations. These carriers are an excellent choice for scale-up projects where process development timelines are limiting.

Collagen Coated

Collagen, a normal component of the extracellular matrix produced by attached cells, has been proven to be an effective promoter of cell attachment and growth for anchorage dependent cell lines.

Experience gained in conventional collagen monolayers is directly applicable to microcarriers. Most cell lines attach and grow rapidly on SoloHill collagen microcarriers.

  • Size range: 90-150 microns
  • Specific gravity: 1.02-1.03, 1.034-1.046
  • May be sterilized by autoclaving with appropriate end user validation, or by gamma irradiation

FACT III

Fast Attachment Collagen Treated (FACT) microcarriers utilize a proprietary surface modification of the collagen layer to enhance performance. Attachment kinetics are improved in comparison to standard collagen coated microcarriers while maintaining the same rapid growth.

  • Size range: 90-150 microns
  • Specific gravity: 1.02-1.03, 1.034-1.046
  • May be sterilized by autoclaving with appropriate end user validation, or by gamma irradiation

Animal Protein Coated Starter Kits

The best microcarrier and attachment conditions may vary between cell types; experimentation will allow the most confident selection of the optimal microcarrier. To accelerate your evaluation process, SoloHill microcarriers are available in a convenient starter kit.

The SoloHill Microcarrier Starter Kit makes it easy to design multivariate experiments which explore the performance of SoloHill microcarriers across media formulations and cell lines. This Standard Starter kit has been designed for general cell culture use with any anchorage-dependent cell line.

Each kit contains 5 g each of: Hillex II, Plastic, Plastic Plus, Star-Plus, Collagen Coated, and FACT III microcarriers
