These findings demonstrate that the choice of culture media impacts the biological response of KC in a manner that persists through differentiation in the same media. Independently of the measurement method, you should be familiar with the BeerLambert law, so that you are aware that the optical density ( absorbance ) of the staining to be measured. Figure 5: Quantification of western blot signals by using ImageJ. However, this method could be highly subjective and presents a variation source when non-uniform background is obtained. Electrophoretic gels such as Western blots need frequently to be quantified in order to translate biochemical results into statistical values (see Gels ). 4.9.8 Protein quantification by western blotting. Hematoxylin and eosin staining at day 5 post differentiation demonstrated greater epithelial thickness in KC cultured in Defined and KGM2 compared to KSFM. The usual method for Western blot quantification by ImageJ involves determination of a rolling ball radius value that adjusts the best background subtraction under the observer criteria.

and western blot quantification (by software programs such as ImageJ). KC cultured in KGM2 and Defined developed significantly higher TEER than in KSFM and when treated with IL-4&13 or IL-17A, we observed variable responses. Western blot loading control antibodies, actin, tubulin, vinculin, GAPDH, PCNA. KC barrier function was measured by transepithelial electrical resistance (TEER). Elevated expression of differentiation markers was observed in cells cultured in either KGM2 or Defined media compared to KSFM. KC differentiation was assessed by Western blot for claudin-1 (CLDN1), occludin (OCLN), cytokeratin-10 (CK10), and loricrin (LOR). Note: western blots are semi quantitative so. Choose the Rectangular Selections tool from the ImageJ toolbar. The inverting LUT ensures that dark bands will be recorded as higher density values. The information along the top of the image indicates that the image is currently in 8-bit mode, using an inverting LUT (look-up table). We observed qualitative and quantitative differences in proliferation KC cultured in Defined had significantly lower proliferative capacity. quantification of protein extracts prior to western blotting is crucial first step in generation of accurate data. A fabricated western blot image opened in ImageJ. We screened available media on the KC line N/TERT2G and found biological responses varied considerably across three culture media: KSFM, KGM2, and Defined. Watch the video explanation about Quantification of western blot using imageJ for beginners.

The COVID-19 pandemic resulted in supply chain shortages necessitating substitutions to standard lab protocols, which resulted in many labs having to use different culture media than they typically use. Here you may to know how to measure band intensity in imagej. Various culture media are used to propagate keratinocytes (KC) in vitro.
