Introducing Our New SOP on Skeletal Muscle Fiber Typing
We are excited to announce the release of our latest Standard Operating Procedure (SOP) titled “Skeletal Muscle Fiber Typing & Cross-Sectional Area Analysis using Immunofluorescence Staining for Mice,” developed by our Basic Science Trainee Committee(opens in new tab) (BSTC) member Shatha Atieh(opens in new tab), Phd Student at uOttawa. This SOP aims to provide a comprehensive, step-by-step protocol for staining and analyzing skeletal muscle fibers from any muscle group in various mouse models.
Key Protocol Features
This SOP includes detailed methods for quantifying fiber-type composition using immunofluorescence staining to detect myosin heavy chain (MyHC) isoforms in individual fibers. Commonly used primary antibodies include MyHC-I, MyHC-IIA, and MyHC-IIB, along with laminin for measuring cross-sectional areas (CSA), providing insights into muscle function and health.
Furthermore, the SOP guides researchers in assessing changes in muscle fiber size due to various factors such as disease or exercise by measuring the CSA of individual muscle fibers and visualizing fiber size distributions through statistical analysis.
We invite all researchers to download the full SOP below:

Visit Our SOP Library
As our SOP Library continues to grow, we are inviting contributions from across the Canadian neuromuscular community. If you have SOPs that could support shared learning and strengthen research practices nationwide, we encourage you to get involved, review our current collection and download our SOP template(opens in new tab). For more information about sharing your SOPs with the us, please contact Erin Beattie(opens in new tab), our Network Manager.

Save the Date: 2027 NMD4C-RARE.Qc Basic Science Research Summer School
NMD4C and RARE.Qc are pleased to announce the 2027 NMD4C–RARE.Qc Basic Science Research Summer School, will take place May 12-14, 2027, at the Université du Québec à Trois-Rivières (UQTR). The Summer School will bring together graduate students, postdoctoral fellows, and early-career researchers for hands-on training workshops, scientific lectures, trainee presentations, networking opportunities, and engagement with leading experts in neuromuscular and rare disease research.
Now Open: 2027 Postdoctoral Research Fellowship Funding Competition
Deadline: Oct 14 2026 | We are happy to announce that applications for the 2027 Postdoctoral Research Fellowship Funding Competition, in partnership with Muscular Dystrophy Canada, is now open. This annual funding competition awards salary support to early-career scientists in interested in advancing their postdoctoral studies in neuromuscular disease (NMD) research.
Congratulations to our 2026 Collaborative Research Training Award Recipients!!!
We are excited to announce the recipients of the 2026 NMD4C Collaborative Research Training Awards, which supports Canadian trainees in their efforts to advance neuromuscular disease research while strengthening national collaboration among neuromuscular research laboratories.
