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.
A review. The interplay between carbohydrates, lipids, and proteins dets. the stability and flexibility as well as the adhesive and responsive features of the surfaces of all cells. The mol. understanding of the interactions among and between the different ...
NOVELTY - Determining a receptor-ligand interaction involves repeatedly contacting a cell comprising a receptor, with a ligand, of the receptor in which the ligand has a fluorescence labeling group and binds reversibly to the receptor under conditions in w ...
Microinjection is a gene transfer technique enabling partial control of plasmid delivery into the nucleus or cytoplasm of cultured animal cells. Here this method was used to establish various recombinant mammalian cell lines. The injection volume was estim ...
Fluorescent protein expressing cells with very high fluorescence are described as well as a method to obtain such cells. The fluorescence of such cells can be as high as about 1000 times the auto-fluorescence of the respective host cell. Due to the high fl ...
Recombinant proteins are gaining in importance for therapeutic applications. The proteins are expressed in stable cell lines, within which recombinant DNA has incorporated into the host cells genome. Identification and isolation of extremely high producers ...
We have prepared transgenic mice whose T cells constitutively express a chimeric receptor combining extracellular human IL-4R and intracellular IL-2Rbeta segments. This receptor can transmit IL-2/IL-15-like signals in response to human, but not mouse, IL-4 ...
This study correlates the fluorescent signal from stable recombinant CHO cell lines expressing the green fluorescent protein (GFP) at high levels with biomass or cell number, extending the use of fluorescent proteins to applications and assays where cell g ...
Neurotrophic factors which act on motor neurons may provide an efficient treatment for amyotrophic lateral sclerosis. In order to overcome the difficulty of administering proteins into the central nervous system, it is possible to use a gene therapy approa ...
Among the molecular mechanisms that control the cell division cycle, proteolysis has emerged as a key regulatory process enabling cells to pass critical check points. Such proteolysis involves a cascade of enzymes including a multisubunit complex termed 26 ...

The invention relates to a device for dispensing droplets comprising a first channel (8, 10), known as the main channel, for circulating a first liquid flow, a second channel (12, 13) for circulating fluid, forming an intersection area (27) with the first ...
