MyoCult-SF Attachment Substrate

A defined, xeno-free coating reagent from STEMCELL Technologies engineered to support the attachment and expansion of primary human skeletal muscle myoblasts under serum-free culture conditions. The substrate is applied as a thin aqueous film onto standard tissue-culture-treated plasticware, priming the growth surface so freshly isolated satellite cells or cryopreserved myoblasts adhere efficiently without the need for animal-derived matrices such as collagen, gelatin, or Matrigel. It pairs with the MyoCult-SF Expansion Medium, creating a fully defined, animal-component-free pipeline for generating large numbers of myogenic progenitors from small biopsy specimens or dissociated skeletal muscle tissue. Each unit arrives in a single-use vial; working aliquots should be prepared under aseptic conditions and stored refrigerated between uses to preserve lot-to-lot consistency across multiple culture sessions. The substrate is for research use only and supports in vitro applications including satellite cell biology, modeling of muscular dystrophies and sarcopenia, CRISPR or siRNA-based gene-editing experiments in myogenic progenitors, and downstream differentiation into multinucleated, contractile myotubes for functional assays, electrophysiology, and high-content drug screening. Researchers replacing traditional biological coatings with this defined substrate benefit from reduced batch variability, a clean background for downstream molecular readouts such as qPCR and RNA-seq, and a workflow that aligns with regulatory expectations for downstream cell transplantation studies.
