Amniotic membrane is commonly exploited in several surgical procedures. Despite a freeze preservation period, it is reported to retain wound healing, anti-angiogenic, antiinflammatory and anti-scarring properties; however, little is known about the active protein content. 2-DE analysis of transplant-ready amniotic membrane (TRAM) was performed. The effects of preservation and processing on amnion proteome were investigated, and the major proteins in the TRAM characterized using mass spectrometry and immunoblotting. This identified a spectrum of proteins including thrombospondin, mimecan, BIG-H3, and integrin alpha 6. Preservation compromises cellular viability resulting in selective elution of soluble cellular proteins, leaving behind extracellular matrix-associated and cell structural proteins. A number of key architectural proteins common to the architecture of the ocular surface were demonstrated in AM, which are involved in homeostasis and wound healing. Handling procedures alter the protein composition of amniotic membrane prepared for transplantation. Without standardization, there will be inter-membrane variation, which may compromise the desired therapeutic effect of transplant ready amniotic membrane.
