Low molecular weight protamine acetate (LMWP acetate;TDSP5 acetate) is a truncated arginine-rich protamine peptide, which also acts as an antidote for heparin/low molecular weight heparin and a cell-penetrating delivery vector. Low molecular weight protamine acetate neutralizes heparin-induced anticoagulant activities, including aPTT, anti-Xa and anti-IIa activities. Low molecular weight protamine acetate translocates across mammalian cell membranes, delivers conjugated impermeable molecules through tumor tissues, enhances the skin permeability of conjugated epidermal growth factor, and accelerates wound healing when conjugated with epidermal growth factor. Low molecular weight protamine acetate retains the in vitro cell proliferation activity of conjugated EGF, and also enables site-specific conjugation with peptides or proteins via genetic recombination. Low molecular weight protamine acetate can be used in studies related to colon cancer, skin wounds and diabetic skin wounds .

Melimine is an antimicrobial peptide with broad-spectrum antimicrobial activity against Gram-negative/Gram-positive bacteria, fungi and protozoa. Melimine neutralizes endotoxin activity by interacting with the phosphate groups of lipid A, depolarizes and permeabilizes the cytoplasmic membrane of *Pseudomonas aeruginosa*, and induces bacterial lysis. Melimine exerts additive antiviral effects against H1N1 and MHV-1 when used in combination with RK610. Melimine retains its antimicrobial activity when conjugated to polymer and titanium surfaces. Melimine can be used in infection-related research .
