The morphogenetic movements of the ectoderm during neurulation include: (1) the movements taking place within the neural plate, which becomes longer and more concentrated in a medio-lateral direction (Jacobson, 1962); and (2) those found in the lateral epidermis layer which, in an epibolic way, moves in a dorsal direction, thus exerting a pushing effect on the lateral edges of the neural plate ...

To attempt to locate functionally important regions of the interferon (IFN) molecule, recombinant human IFN-alpha 2 was subjected to proteolytic digestion. The bacterial proteinase thermolysin produced two major complementary fragments, HuIFN-alpha 2-(1-110) and HuIFN-alpha 2-(111-153). After reduction with 2-mercaptoethanol and separation of the two major fragments on NaDodSO4/polyacrylamide g...

Bacillus sp. ASX42 isolated from soil samples of Lake Van shores, Turkey, and the strain producing cellulose-free xylanase enzyme with an optimum pH 9.0, at 60ºC. The molecular weight was estimated as 66 kDa on SDS PAGE analysis. Thermal stability detected average 68.7% 4-60ºC 60% 65-95ºC while observed about 90% between 3.5-13.0 for 15 min. As HgCl2 presented a strong inhibitor activity, Cobal...
