amsbio a leading supplier of Mouse Embryonic Fibroblasts (MEFs) to support the growth of undifferentiated mouse or human embryonic stem cells (ESCs) and induced pluripotent stem cells (iPSCs). Meticulously derived and
comprehensively tested on mouse and human ES stem cells to ensure robust and consistent performance with every lot.
We offer CF-1, DR4, Neo-resistant and SNL (STO) feeder cells, supplied either as untreated cells (P2) for
further expansion and treated cells that can be directly used as a feeder layer.
Benefits:
- Minimise Lot to Lot variation
- Eliminate Contamination
- Save Time
Every Lot of feeder cells is tested to support embryonic and IPS cells over several passages.

Quality Control:
- 1. PCR‐based assay for 22 mouse pathogens with sensitivity equal to or greater than traditional MAP Testing.
- 2. Direct inoculation and culture of blood agar plates, thioglycolate broth, tryptocase soy broth, and sabaoraud dextrose agar to check for bacterial and fungal contamination.
- 3. PCR‐based assay sensitive to the detection of species typically found as contaminants of cell culture.
- 4. Sparse population of mouse ES cells is plated and observed for overall plating efficiency, colony morphology and immunocytochemistry.
- 5. Qualification based on the morphology, growth, and immunocytochemisty of human ESC cultured for multiple passages.
