The technique is often used in research to separate and identify proteins. Western blotting is an important technique used in cell and molecular biology. Once students have done a series of centrifugations and used liquid nitrogen to snap freeze the pigments, it’s time to find out if the pigment extracts can absorb green light. Most labs will have a centrifuge! This technique “is used to collect cells, to precipitate DNA, to purify virus particles, and to distinguish subtle differences in the conformation of molecules” (2).Ĭentrifugation is used in Labster’s Pigment Extraction simulation: Use photosynthesis to produce biofuel and reduce pollution. It’s one of the most useful and frequently employed techniques in the molecular biology laboratory. CentrifugationĬentrifugation is a process that uses centrifugal force to separate particles from a solution. They’ll also be introduced to the aseptic technique. They’ll perform the different steps to keep them healthy by using a standard cell culture protocol for eukaryotic cells. In the Cell Culture Basics simulation, students will learn how to culture cells in a controlled environment. “Cell culture is one of the major tools used in cellular and molecular biology, providing excellent model systems for studying the normal physiology and biochemistry of cells (e.g., metabolic studies, aging), the effects of drugs and toxic compounds on the cells, and mutagenesis and carcinogenesis” (1). We’ve identified 7 common techniques and recommended a virtual lab for each option to prepare students in a flipped lab style.Ĭell culture is the removal of cells from an animal or plant in an artificial environment, generally for the purposes of research.

Upon getting to class, they’re more knowledgeable about the topic and can dive right in.

Have you tried a flipped lab approach to teaching? Students watch a video, do a simulation, or prepare for the practical lab with homework. Preparing students to learn about molecular biology techniques doesn’t have to be challenging.
