Ibarguren, Izaskun; Villamarín, Antonio – Journal of Biological Education, 2017
All the cells of higher organisms have the same DNA but not the same proteins. Each type of specialised cell that forms a tissue has its own pattern of gene expression and, consequently, it contains a particular set of proteins that determine its function. Here, we describe a laboratory exercise addressed to undergraduate students that aims to…

Punnoose, Jibin Abraham; Halvorsen, Ken; Chandrasekaran, Arun Richard – Journal of Chemical Education, 2020
There is a disconnect between the cutting-edge research done in academic laboratories, such as nanotechnology, and what is taught in undergraduate laboratories. In the current undergraduate curriculum, very few students get a chance to do hands-on experiments in nanotechnology-related fields, most of which are through selective undergraduate…

Teerasong, Saowapak; McClain, Robert L. – Journal of Chemical Education, 2011
We have developed an undergraduate laboratory activity to introduce students to microfluidics. In the activity, each student constructs their own microfluidic device using simple photolithographic techniques and then uses the device to separate a food dye mixture by electrophoresis. Dyes are used so that students are able to visually observe the…

Jiao, Li; Xueli, Li; Xiujuan, Shi; Song, Jia; Jie, Xu; Lixia, Lv; Wenzhuo, Yang; Lei, Xu – Biochemistry and Molecular Biology Education, 2019
For medical students, we combine the laboratory practice with clinical applications by developing biochemical and molecular biology experiments. In this experiment, students first collect their own buccal epithelial cells by a noninvasive mouthwash method. Then, they extract genomic DNA and perform polymerase chain reaction (PCR) to amplify…

Pirinelli, Alyssa L.; Trinidad, Jonathan C.; Pohl, Nicola L. B. – Journal of Chemical Education, 2016
Polyacrylamide gel electrophoresis (PAGE) is commonly taught in undergraduate laboratory classes as a traditional method to analyze proteins. An experiment has been developed to teach these basic protein gel skills in the context of gluten protein isolation from various types of wheat flour. A further goal is to relate this technique to current…

De Mattos, J. C. P.; Dantas, F. J. S.; Caldeira-de-Araujo, A.; Moraes, M. O. – Biochemistry and Molecular Biology Education, 2004
Good quality scientific teaching depends on the ability of researchers to translate laboratory experiments into high school and undergraduate classes, bridging the advanced and basic science with common knowledge. A fast-growing field in biomedical sciences is oxidative stress, which has been associated to several diseases, including cancer and…

Tweedie, John W.; Stowell, Kathryn M. – Biochemistry and Molecular Biology Education, 2005
A two-session laboratory exercise for advanced undergraduate students in biochemistry and molecular biology is described. The first session introduces students to DNA quantification by ultraviolet absorbance and agarose gel electrophoresis followed by ethidium bromide staining. The second session involves treatment of various topological forms of…
