Chattez avec Graph Search
Posez n’importe quelle question sur les cours, conférences, exercices, recherches, actualités, etc. de l’EPFL ou essayez les exemples de questions ci-dessous.
AVERTISSEMENT : Le chatbot Graph n'est pas programmé pour fournir des réponses explicites ou catégoriques à vos questions. Il transforme plutôt vos questions en demandes API qui sont distribuées aux différents services informatiques officiellement administrés par l'EPFL. Son but est uniquement de collecter et de recommander des références pertinentes à des contenus que vous pouvez explorer pour vous aider à répondre à vos questions.
The smaller isoform of the GABA-synthesizing enzyme, glutamic acid decarboxylase 65 (GAD65), is unusually susceptible to becoming a target of autoimmunity affecting its major sites of expression, GABA-ergic neurons and pancreatic β-cells. In contrast, a hi ...
The authors have prepd. beta-peptides I and II which contg. unlike-beta2,3-amino acids. The structures of beta-peptides I (prepd. in soln.) and II (prepd. on solid-phase) are reported. ...
Anti- V.cholerae monoclonal IgA antibodies have been produced using a hybridoma cell line (Zac3) grown in RPMI medium contg. 10% Fetal calf serum (FCS) and a completely defined protein- free medium. The latter has been optimized with respect to amino acid, ...
The puromycin-sensitive aminopeptidase (PSA) is thought to contribute to the degradation of enkephalins. Besides being the most abundant aminopeptidase in the brain, PSA is expressed in other organs as well. From a human fetal brain cDNA library, we have i ...
Comprehensive and cGMP suitable bioprocess monitoring is still a challenge in microbial fermn. and cell culture process development. This paper discusses the exploitation of in-situ mid-IR spectroscopy in combination with partial least-squares anal. to mon ...
The chloro-bridged complexes [CpMCl2]2 (Cp = C5Me5, M = Ir, Rh), [(p-cymene)RuCl2]2, [(C6Me6)RuCl2]2, and [(Et3P)PdCl2]2 react with SAMP by cleavage of the chloro bridges to give the corresponding monomeric h1-SAMP complexes. The x-ray structural detns. ...
Achieving practical biotechnol. processes for the prodn. of fine chems. requires optimization of metabolic fluxes. Attempts to alter the fluxes through a given pathway may be frustrated by compensatory changes in coupled pathways or by unexpected effects s ...
The formation of 4-hydroxy-2,5-dimethyl-3(2H)-furanone (HDMF) and 2(or 5)-ethyl-4-hydroxy-5(or 2)-methyl-3(2H)-furanone (EHMF) from pentose sugars was studied in Maillard model systems. The amts. generated at 90 DegC for 1 h were detd. by isotope diln. ass ...
The chloro-bridged complexes [CpMCl2]2 (Cp = C5Me5, M = Ir, Rh), [(p-cymene)RuCl2]2, [(C6Me6)RuCl2]2 and [(PEt3)PdCl2]2 react with SAMP by cleavage of the chloro bridges to give the corresponding monomeric h1-SAMP complexes. The x-ray structural detns. o ...
A chemically-defined protein-free medium (FMX-Turbodoma) has been improved for the production of monoclonal IgA antibodies by hybridoma cells, using a systematic method. Cell growth rate, IgA production, activity and molecular weight pattern have been used ...
