Isolation of a diterpenoid substance with potent neuroprotective activity from fetal calf serum

Isolation of a diterpenoid substance with potent neuroprotective activity from fetal calf serum.

Excess activation of glutamate receptors and production of free radicals including nitric oxide may result in severe and irreversible damage to the mammalian central nervous system (CNS), but endogenous defense systems that protect neurons from these insults are poorly understood. Here, we purified and isolated a neuroprotective substance, which has been named "serofendic acid," from a lipophil...

Isolation from fetal bovine serum of an apolipoprotein-H-like protein which inhibits thymidine incorporation in fetal calf erythroid cells.

A 46 kDa heparin-binding protein which inhibits thymidine incorporation in cultures of fetal calf liver erythroid cells was isolated from fetal bovine serum by affinity chromatography on heparin-Sepharose, ion-exchange chromatography, gel filtration and reversed-phase h.p.l.c. The N-terminal sequence of the first 22 amino acids showed 81% identity with the published sequence of human apolipopro...

Use of chicken serum as a good replacement for the fetal calf serum in cultivation of promastigotes of Leishmania major

Genus Leishmania is a protozoan parasite that causes different severe diseases. Fetal Calf Serum (FCS) is the major part of the Leishmania culture media, for mass cultivation and the most expensive ingredient in these media. In the present work, the efficacy of chicken serum was evaluated in Leishmania culture media. The results indicated that, the (10%) chicken serum enriched culture medium su...
