GECKO™ – adherence solution
£165.00
GECKO™ is a chemically defined, animal component free mix of adhesion factors to support adherent cell culture. Fetal bovine serum (FBS) contains a complex mixture of adhesion-promoting factors that enable attachment on standard tissue culture plastic. When culturing cells in serum-free or chemically defined media, these adhesion cues are often no longer present. As a result, many adherent cell types require an explicit surface strategy to support attachment, spreading, and early survival.
GECKO™ has been validated as a defined, animal-free coating which supports a broad range of adherent cell types.

Product background
Many cell types require the use of an adherence coating when culturing cells with FRS™ Pioneer—or any serum-free media—on standard TC plasticware. GECKO™ is a chemically defined and animal component free mix of lyophilized adhesion proteins that facilitate attachment of many adherent cell types to standard cell culture plates. GECKO™ supports serum-free adherence of most cell lines traditionally cultured in FBS without a coating. A minority of cell lines will perform optimally with a recombinant vitronectin coating (see below).
GECKO™ was developed to pair with FRS™ Pioneer as part of a fully chemically defined culture workflow.
Coating workflow for culturing adherent cells with FRS™ Pioneer
Using GECKO™ with FRS™ Pioneer allows:
- Separation of growth support (media) from adhesion (surface)
- Greater experimental control
- Reduced background from undefined serum components
GECKO™ can also be used with other serum-free or reduced-serum media systems.
When to use GECKO™
GECKO™ is a good starting point if you:
- Are transitioning from serum-containing media to serum-free or chemically defined media
- Want a single, animal-free coating compatible with many adherent cell lines
- Prefer a reproducible, defined alternative to serum-based pre-coating
- Are culturing adherent cells with FRS™ Pioneer and require attachment support
GECKO™ Mix (with fibronectin) has been validated with:
- Non-cancer epithelial (CHO, HEK)
- Low TGFβ cancer (MCF7)
- Mesenchymal (NIH-3T3)
- Glioblastoma (U87, A172)
- Renal carcinoma (ACHN)
- Muscle (C2C12)
- Skin (B16-F10)
When to use an alternative coating
You may require a different coating strategy if:
- Your cell line falls into a category previously validated with FRS™ Pioneer for vitronectin coating (see below).
- When culturing your cells in FBS-containing media, you typically use a coating (e.g. collagen, laminin).
- You observe poor attachment, spreading, or survival with GECKO™
In these cases, coatings including but not limited to vitronectin, laminin, fibronectin, collagen, Matrigel or gelatin may be more appropriate.
Vitronectin alone with FRS™ Pioneer has been validated with:
- High TGFβ cancer (A549, H460, SW480, DU145)
- Hepatocyte (Hep2G)
- Normal kidney (MDCK)
- Adenocarcinoma (HT-29)
