The lateral flow immunoassay (LFIA) is a simple and cost-effective rapid diagnostic test designed for the on-site detection of disease biomarkers. In the context of introducing this technique to undergraduate biotechnology students, we propose a comprehensive 5 h laboratory experiment. This experiment covers various aspects, including the…

The COVID-19 pandemic forced many courses to move online, presenting a particular challenge for hands-on laboratory courses. One such course in our Biotechnology track is an advanced Protein Interactions lecture/laboratory course. This 8-week course typically meets for 5 h a week in the laboratory space. For the Fall 2020 version of the course,…

A semester-long, project-based series of laboratory exercises is described that provides practical experience of the upstream and downstream processes involved in monoclonal antibody production. This 6 week project is aimed at final year undergraduate students undertaking primary degrees in biotechnology, biochemistry, or related disciplines.…

Medical, industrial, and basic research relies heavily on the use of viruses and vectors. Therefore, it is important that bioscience undergraduates learn the practicalities of handling viruses. Teaching practical virology in a student laboratory setup presents safety challenges, however. The aim of this article is to describe the design and…

This experiment describes a simple protocol for teaching acid-base titrations using potentiometry, conductivity, and/or photometry to determine end points without an added indicator. The chosen example examines the titratable acidity of a red wine with NaOH. Wines contain anthocyanins, the colors of which change with pH. Importantly, at the…

Background: Engineering programs must equip students to solve open-ended workplace problems. However, the literature points to actual or potential difficulties faced by students in solving open-ended or complex problems. During Fall 2014, the authors' students experienced difficulties in solving open-ended bio-signals laboratory problems of…

A multiweek protein purification suite, suitable for upper-division biochemistry or biotechnology undergraduate students, is described. Students work in small teams to isolate the enzyme lactate dehydrogenase (LDH) from a nontraditional tissue source, mammalian blood, using a sequence of three column chromatographic procedures: ion-exchange, size…

An integrative laboratory study addressing fundamentals of enzyme catalysis and their application to reactors operation and modeling is presented. Invertase, a ß-fructofuranosidase that catalyses the hydrolysis of sucrose, is used as the model enzyme at optimal conditions (pH 4.5 and 45 °C). The experimental work involves 3 h of laboratory time…

As advances in biotechnology and molecular biology rapidly expand in research settings, it is vital that we continue to prepare high school students to enter and thrive in those modern laboratories. This multistep, inquiry-based lab describes highly adaptable methods to teach students not only current molecular techniques and technologies, but…

A blended approach encompassing problem-based learning (PBL) and structured inquiry was used in this laboratory exercise based on the congenital disease Osteogenesis imperfecta (OI), to introduce commonly used techniques in biomolecular analysis within a clinical context. During a series of PBL sessions students were presented with several…

Piezoelectric actuators (or piezoactuators) are known for their nanoresolution and high-speed positioning capabilities. Therefore, they are used in scanning probe microscopes and in the design of innovative surgical tools and biomedical devices. The expected growth of engineering jobs in the nano- and bio-related fields, in which piezoactuators…

Open-ended, inquiry-based multiweek laboratory exercises are the key elements to increasing students' understanding and retention of the major biological concepts. Including original research into undergraduate teaching laboratories has also been shown to motivate students and improve their learning. Here, we present a series of original…

Expression proteomics has become, in recent years, a key genome-wide expression approach in fundamental and applied life sciences. This postgenomic technology aims the quantitative analysis of all the proteins or protein forms (the so-called proteome) of a given organism in a given environmental and genetic context. It is a challenge to provide…

Biotechnology is a fairly new concept for middle school students as well as teachers. If the latest craze of TV shows focused on crime scene investigation events were not so popular, the term and concept might be even obscure to the public. There is an increased presence of biotechnology in our daily surroundings that makes it practical and…

Describes a freshman biology laboratory project that uses the polymerase chain reaction to introduce students to the interrelationship between biology and chemistry. Students must develop their own experimental protocol, perform calculations introduced in freshman classes, and evaluate group dynamics. (Author/WRM)
