IGF-binding proteins bind IGF-1 with high affinity, which keeps it in circulation far longer than it would otherwise persist and governs how much reaches receptors at any moment. Different family members behave differently and are expressed differently between tissues.
Some have been reported to act on their own, independently of IGF binding, which is a reminder that they are participants rather than packaging.
Cells in culture secrete binding proteins into the medium. Add native IGF-1 and an unknown fraction is captured before it reaches a receptor, so the nominal concentration overstates the exposure — by an amount that varies with cell type, density and time.
This is the specific problem LR3 was designed around, and it is why the analogue is so common in that setting.
Using LR3 makes exposure more predictable by taking the binding proteins out of the picture. If the question involves how availability is regulated, that is the question being deleted rather than controlled.
Which material is right follows from the question, exactly as with a blend versus single vials: the design decides, not the convenience.
IGF-1 LR3 is supplied here as a research material with batch documentation available on request.
