Indications for Use
MoFi is a liquid culture medium intended for human ex vivo tissue and cell culture processing applications.
Device Story
MoFi is a liquid basal culture medium based on Iscove's Modified Dulbecco's Medium (IMDM) and cell-degradable polysaccharide; contains water, carbohydrates, amino acids, and salts. Used in laboratory settings for ex vivo processing of suspension or adherent primary cells and cell lines. Operators (technicians/researchers) mix the basal medium with additives (serum, L-glutamine, sodium pyruvate, growth factors) to create a complete medium. The medium provides nutrients and energy to support cell survival, growth, and maintenance. The product is for single-use, aseptically processed, and requires storage at 2-6°C. It is not for injection into the human body.
Clinical Evidence
Bench testing only. Performance testing confirmed MoFi supports cell viability and normal morphology across four cell types: suspension primary cells, suspension cell lines, adherent primary cells, and adherent cell lines. Testing verified sterility (negative), endotoxin levels (< 1 EU/mL), and absence of mycoplasma. Biocompatibility evaluated per ISO 10993-1.
Technological Characteristics
Basal medium based on IMDM and cell-degradable polysaccharide. Composition: water, carbohydrates, amino acids, salts. Form factor: 80 mL liquid in PETG bottle with HDPE closure. Storage: 2-6°C. Aseptically processed. No software or electronic components.
Indications for Use
Indicated for human ex vivo tissue and cell culture processing applications. Intended for use by or on the order of a physician.
Regulatory Classification
Identification
Tissue culture media for human ex vivo tissue and cell culture processing applications consist of cell and tissue culture media and components that are composed of chemically defined components (e.g., amino acids, vitamins, inorganic salts) that are essential for the ex vivo development, survival, and maintenance of tissues and cells of human origin. The solutions are indicated for use in human ex vivo tissue and cell culture processing applications.
Special Controls

### 5. Shelf Life
According to the stability test's result, shelf life for MoFi is recommended to be 9 months.
### 6. Biocompatibility
The biocompatibility evaluation was conducted in accordance with the FDA Guidance "Use of International Standard ISO 10993-1,"Biological evaluation of medical devices - Part 1: Evaluation and testing within a risk management process.
### 7. Performance Testing
All batches tested met the acceptance criteria of performance testing. The residual endotoxin is well controlled. No bacteria and mycoplasma were detected. The residues of plasticizers, heavy metals and particles are not detected or can be safely ignored.
### 8. Conclusion
MoFi and Knockout™ SR Medium and Knockout™ SR Xenofree Medium are used for human ex vivo tissue and cell culture processing applications and have the same/similar container, storage temperature, efficacy (generic cellular growth and maintenance) and safety (consistency in chemical content and formulation, biocompatibility with cells, and purity). Their efficacy in supporting the survival, growth, development, and maintenance of human cells or tissue culture systems has been well established in scientific publications included in this submission. These products (MoFi and Knockout™ SR Medium and Knockout™ SR Xenofiree Medium) are manufactured in accordance with QSR requirements and are labeled as aseptically processed. Thus, MoFi are substantially equivalent to the legally marketed device (K100616) intended for the human ex vivo tissue and cell culture processing applications.
