Understand the supplier's protocol for quality rejects, returns, and liability
For description of ARNA response to intrapelvic injection of GLP-1 (3 M in saline, Enzo Life science, Farmingdale, NY), ARNA was expressed as a percent changes from the baseline value and also normalized to maximal ARNA induced by intrapelvic injection of capsaicin (100 M in 5% ethanol and 95% saline, Sigma, Saint Louis, MO) thus expressed as a percent of ARNAmax as shown previously [24, 26, 34]
Consequently, researchers designing head-to-head comparison protocols between the two formulations source both from one supplier with batch-matched documentation and avoid the inter-vendor variability that would otherwise confound their results
