The Claim

In mice, the monoclonal antibody SRK-015 selectively inhibits myostatin activation without cross-reacting with GDF11, Activin A, BMP9, BMP10, or TGFβ1, demonstrating that targeting precursor forms enables greater specificity than antibodies targeting mature myostatin.

These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.

How it works
1 study reviewed
In plain English

In mice, the antibody SRK-015 blocks myostatin activation without affecting related proteins GDF11, Activin A, BMP9, BMP10, or TGFβ1, showing that targeting the precursor form of myostatin achieves higher specificity than targeting the mature form.

See the scientific wording

In mice, the monoclonal antibody SRK-015 selectively inhibits myostatin activation without cross-reacting with GDF11, Activin A, BMP9, BMP10, or TGFβ1, demonstrating that targeting precursor forms enables greater specificity than antibodies targeting mature myostatin.

Why this might work

A specific antibody binds to the inactive form of myostatin before it gets activated, preventing a molecular cutter from splitting it into its active version. Without the active form, muscles stop breaking down and start growing larger and stronger.

    This study shows that SRK-015 is like a smart key that only fits the lock of myostatin before it becomes active, leaving other similar proteins alone—making it more precise than older keys that opened multiple locks by mistake.
