between the Genotype and Phenotype of Drosophila melanogaster Eye Pigment Mariam Rahmanyar 100486882 T.A: Zahra Mortaji BIOL 2020 Results: Our TLC plate showed all colours expressed by the pteridine pigments for the wild-type Drosophila as expected (Figure 1). The sample A mutant which was a bright-red eye mutant also expressed the same pigments as our wild-type. Compared to the wild type‚ sample A pigment spots were lower intensity in colour under the UV light (Figure 2)

Separation of Plant Pigments from Tomato Paste ABSTRACT In column chromatography a mixture is dissolved in a solvent and poured over a column of solid adsorbent then eluted with the same or a different solvent. This method is often used for preparative purposes; when a relatively large amount of the mixture and the components need to be isolated. The two main pigments in tomato paste mixture are the yellow-orange β-carotene and the red lycopene. The colors of these pigments are because of

Lab #3: Ion Exchange Chromatography Objective The purpose of this experiment was to separate proteins on the basis of their net charge at a particular pH. In cation exchange chromatography positively charged molecules are attracted to a negatively charged column. Conversely‚ in anion exchange chromatography‚ negatively charged molecules are attracted to a positively charged column. Experimental results could be monitored in a predictable way by controlling running pH‚ salt concentration‚ and by
