Two immunoassays, one preferring the 22 kDa form and one recognising the pituitary mixture, are run on the same sample and the ratio compared with population limits. The window is short because the exogenous protein clears within hours to a day, but the chemistry is direct: a ratio that cannot arise from the pituitary alone.
It depends on the fact that recombinant material is a single isoform, which is also an analytical fact about the product.
IGF-1 and the amino-terminal propeptide of type III procollagen both increase in response to growth hormone and stay raised for days to weeks. A score combining the two with age is compared with a threshold. This extends the detection window at the cost of indirectness. Published validation work includes Powrie and colleagues in 2007.
Both markers are also used clinically as readouts of growth hormone action.
Because the isoform composition of recombinant somatropin — one species, 22 kDa — is part of what the product is, and the detection science is the clearest demonstration of it.
Somatropin is supplied by REVIVE LAB UAE for laboratory research use only, with identity and purity documented for the batch. It is not for human or veterinary use, and no dosing, administration or protocol guidance is provided.
