Fig. 2From: Targeted delivery of pentagalloyl glucose inhibits matrix metalloproteinase activity and preserves elastin in emphysematous lungsProtection of elastin by PGG from elastase challenge ex vivo. A Concentration dependent elastase inhibition with PGG, as determined using AAAPVN assay. B % tissue weight loss in control and PGG fixed mouse lung samples. C Elastin quantification in control and PGG fixed lung samples following elastase challenge. D–E phenol stain of histological sections of control and PGG fixed lungs where PGG stains black.
