RNAi knockdown of either col or col did not result in increased permeability S4 Figarguing that these collagens may be down-regulated due to CEH disruption, but their down-regulation in itself is insufficient to create a permeable cuticle. Validation of experimental approach Scraping off the cells of a culture dish is of course a highly artificial procedure that may not be a valid surrogate for having undifferentiated cells in addition to differentiated adipocytes on one culture plate. C Expression in the intestine is not clearly observed in the L3 larval stage or before. Yellow circles indicate regions used for intestinal fat quantification. Our protocol has a wide dynamic range and produces linear results from no differentiated cells on a culture plate to a plate fully covered with adipocytes. Cheung The general concept of the Nile red assay to be used was adopted from literature. The changes of the biomass specific optical signal were most likely caused due to morphology dependent light scattering characteristics of the cells. Ratio of oxidized over reduced RoGFP2 before and after addition of exogenous stress.
Oil red O staining can be used to assess the degree of differentiation. However, the validity of this method for quantitative analysis has not yet. Here, we describe a novel label-free LD quantification technique. Staining based measurement of lipid content using Oil Red O LG.

A dash signifies that no information was given, which may indicate that a certain step was either not performed, or performed according to the base protocol, or performed differently but not reported.

|Adipocyte cell culture is an important tool for mechanistic studies of energy metabolism. Hence, the interaction between CEH and UNC drives both vitellogenesis and cuticle permeability in a way that originates from the primary lipid-metabolizing organ in C.

By now, a large number of protocols using Nile red for the quantification of intracellular lipids have been developed, while especially dye permeation was identified as a major bottleneck. Bettina J.

On the other hand, linear regression of the data obtained using our optimized protocol produces extremely small p values regardless of the culture plate format used Figs. Quantitative oil red O staining of differentiated adipocytes. The performance of the method is independent of the culture plates used. As expected [ 3 ], all 6 VIT proteins were drastically down-regulated, and they emerged as the 6 most differentially regulated proteins in our dataset.
