خلاصه	The bone morphogenetic protein (BMP) release assay measures the kinetics and amount of BMP elution from a biomaterial carrier over time. BMP-2, BMP-6, BMP-7, and BMP-9 are potent osteoinductive growth factors discovered by Marshall Urist in 1965 that trigger bone and cartilage formation. When loaded into scaffolds, hydrogels, or implants, BMPs must be released in a controlled manner to maximize biological effect while minimizing systemic exposure. The release assay quantifies how much BMP is present in the surrounding medium at defined timepoints, enabling optimization of carrier materials and release profiles for bone regeneration and fracture healing applications.	Gel permeation chromatography (GPC), also known as size exclusion chromatography (SEC), is an analytical technique for determining the molecular weight distribution (MWD) and average molecular weight (Mw, Mn) of polymers. The method separates polymer molecules by their hydrodynamic size as they pass through a porous chromatography column: larger molecules elute first (excluded from pores), while smaller molecules are retained longer. Developed by Moore and colleagues in the 1960s, GPC/SEC is now the standard method for characterizing polymer chains, assessing polymer degradation over time, and verifying batch consistency in biomaterial production.
