Sperm-egg plasma membrane fusion during fertilization was studied using guinea pig gametes and mAbs to sperm surface antigens. The mAb, PH-30, highly inhibited sperm-egg fusion in a concentration-dependent fashion. When zona-free of charge eggs were inseminated with acrosome-reacted sperm preincubated in saturating (140 micrograms/ml) PH-30 mAb, the percent of eggs showing fusion was reduced 75

Why is usually that I've gotten actually uninterested in drinking the same proteins shakes each day. What do I mean when I say that protein powders make me sick?
