LabXchange features a freely accessible collection of interactive lessons, simulations, texts, videos, short assessments, and learning modules for biology and chemistry. Created by experts at Harvard University, the content is engaging and easily adaptable to fit most classroom and student learning needs.
This simulation allows users to explore how a protein of interest, red
fluorescent protein, can be purified from cell lysate using hydrophobic
column chromatography.
Dans cette vidéo éducative, les professeurs de lycée Anu Deshpande et Aaron Mathieu expliquent ce qu’est un plasmide et pourquoi c’est un outil utile en biotechnologie.
En este video de capacitación, los profesores de escuela secundaria Anu Deshpande y Aaron Mathieu explican qué es un plásmido y por qué es una herramienta útil en la biotecnología.
Ramona Hurdayal shares with Rob how she entered the field of infectious disease research, where she focuses on human Leishmaniasis, and also reflects on the difference between working with model organisms and human patients. This is “Disease Knows Now Borders,” for The Xchange. A new virtual interview series from LabXchange at Harvard University, the Xchange showcases the diverse roles, projects, and initiatives that make up the intersecting fields of science, education, and health. Hosted by LabXchange Faculty Director Robert Lue, our first season features a range of perspectives on the impact of COVID-19.

When a chemcial reaction occurs in a closed system, it will reach an equilibrium state in which reactants and products are produced at the same rate. This pathway provides resources to undestand the factors that affect chemical equilibrium.
This interactive introduces how mistakes in the genome can cause disease. The gene editing tool CRISPR-Cas9 can correct these mistakes and potentially cure disease.
This pathway makes aware of scientific misconduct and introduces how it can be countered by research integrity.
This simulation provides an opportunity to practice a restriction digest in a
virtual lab setting. Restriction enzymes are used to cut the DNA strands of
two plasmids, producing DNA fragments with complementary sticky ends
that can be reassembled to create a recombinant plasmid.
In this video, Monique demonstrates how to perform a restriction enzyme digest in the lab.
Bu simülasyon, sanal bir laboratuvar ortamında restriksiyon sindirimi ile ilgili uygulama yapma fırsatı sağlamaktadır. Restriksiyon enzimleri, iki plazmidin DNA ipliklerini kesmek için kullanılır ve böylece, bir rekombinant plazmid oluşturmak üzere yeniden bir araya getirilebilen komplementer yapışkan uçlara sahip DNA parçacıkları üretilir.
Diese Simulation bietet die Möglichkeit, einen Restriktionsverdau in einer virtuellen Laborumgebung zu üben. Restriktionsenzyme werden verwendet, um die DNA-Stränge von zwei Plasmiden zu schneiden, wodurch DNA-Fragmente mit komplementären kohäsiven Enden entstehen, die wieder zu einem rekombinanten Plasmid zusammengesetzt werden können.
This scrollable interactive provides an overview of DNA replication and the key enzymes involved, highlighting the role of DNA ligase.
This scrollable interactive shows how DNA ligase can be used in biotechnology to create recombinant plasmids by connecting DNA fragments.
This scrollable interactive explores the different roles that proteins can play in the cell. Categories of proteins covered include transmembrane proteins, proteins that make up molecular machines like cilia and ribosomes, and enzymes. The four levels of protein structure are also discussed.
Ronald Heifetz, who is renowned for defining the adaptive leadership framework, shares his journey from practicing medicine to teaching at the Harvard Kennedy School. We learn about the principle of adaptability, and how it can help us navigate the COVID-19 pandemic. This is “The Mobilization of Adaptability” for the Xchange. A new virtual interview series from LabXchange at Harvard University, the Xchange showcases the diverse roles, projects, and initiatives that make up the intersecting fields of science, education, and health. Hosted by LabXchange Faculty Director Robert Lue, our first season features a range of perspectives on the impact of COVID-19.
This pathway explores the principles of rotational motion, such as rotational intertia, torque and angular velocity. Angular kinematics are explained in a manner analogous to one dimentional kinematics, and the principle of conservation of angular momentum is discussed. Applications of these principles are provided, as well as problems to check for understanding.
In this simulation, proteins are separated by protein gel electrophoresis (or
SDS-PAGE). Specifically, SDS-PAGE is used to separate the polypeptides of
CRSPR-Cas9-edited cell lines.
This video animation describes the effect of the detergent SDS on cellular membranes. SDS is a crucial reagent in SDS sample buffer that is used in protein gel electrophoresis (SDS-PAGE).
This interactive will present the varying applications of the powers of ten within
the metric system to measure the lengths of objects invisible to the eye and
objects out of this world.
We invite children of all ages to create something colorful with these downloadable coloring pages!
