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.
In questa simulazione, gli utenti si eserciteranno a trasformare le cellule
batteriche con un plasmide ricombinante utilizzando il metodo dello shock
termico.
This pathways explores one of the fundamental forces of nature: the Law of Universal Gravitation, first formulated by Isaac Newton. There are explanations of how to use the law to calculate forces between different bodies, as well as some application sof this law. There are questions at the end of the pathway to check for understanding of the topic.
Esta simulação permite aos usuários praticar o uso de uma micropipeta em
um cenário de laboratório virtual. As habilidades enfatizadas nesta
simulação incluem a dispensa de diferentes volumes de líquido com uma
micropipeta P20 e o uso da primeira e da segunda parada.
This scrollable interactive highlights the use of the Scientific Method in Robert Paine’s Keystone Species experiment.
This pathway introduces the concept of vaccination, how vaccines are developed, and the purpose of clinical trials during vaccine development. The coronavirus SARS-CoV-2—which causes COVID-19—serves as an example.
Esta vía demuestra cómo una herramienta fundamental en biotecnología, la electroforesis en gel de ADN, puede utilizarse para verificar la producción exitosa de un plásmido recombinante. Esta vía es compatible con los laboratorios ABE 4 y 4a.
En esta simulación, los usuarios explorarán el modo de utilización de una
técnica denominada electroforesis en gel para verificar que todos los
componentes deseados se hayan incluido en un plásmido recombinante.
In questa simulazione, gli utenti analizzeranno l’utilizzo di una tecnica
chiamata elettroforesi su gel per verificare che tutti i componenti
desiderati siano stati inclusi in un plasmide ricombinante.
Nessa simulação, os usuários irão explorar como usar uma técnica
chamada eletroforese em gel para verificar se todos os componentes
desejados foram incluídos em um plasmídeo recombinante.
In dieser Simulation sehen Teilnehmer die Verwendung einer Methode
namens Gelelektrophorese zur Verifizierung, ob alle gewünschten
Komponenten in einem rekombinanten Plasmid enthalten sind.
This pathway demonstrates how a fundamental tool in biotechnology, DNA gel electrophoresis, can be used to verify successful production of a recombinant plasmid. This pathway supports ABE labs 4 and 4a.
In this simulation, users will explore how to use a technique called gel
electrophoresis to verify that all desired components have been included in
a recombinant plasmid.
Dans cette simulation, les utilisateurs vont découvrir comment utiliser une
technique appelée électrophorèse sur gel pour vérifier que tous les
composants désirés ont été inclus dans un plasmide recombinant.
This pathway provides an introduction to the structure of water and properties of water, such as hydrogen bonding, that make it essential for life. For a deeper look at this topic, we recommend the pathway The Chemical Foundation of Life from the OpenStax textbook Biology for AP® Courses.
This pathway introduces the concept of waves. Properties of waves are defined, such as frequency, wavelength and period. Examples of waves in different media are given, as well as observable properties. Problems are provided to check for understanding.
This video demonstrates the Western blot technique in a laboratory setting. Western blotting is a common technique to visualize proteins with the help of specific antibodies.
This interactive illustrates the steps of the Western blot technique that allows us
to visualize proteins with the help of specific antibodies.
In this simulation, the Western blot technique is used to determine the
expression of a particular protein in human cells. Specifically, the Western
blot visualizes the expression levels of the macrophage co-receptor CCR5
in CRISPR-Cas9 edited cell lines.
In this teaching video, high school teachers Anu Deshpande and Aaron Matthieu explain what a plasmid is and why it is a useful tool in biotechnology.
This pathway explores the fundamental concept of energy, and how energy can be transferred between objects. Different types of energy are defined, and the law of conservation of energy is explained. Simple machines are explained as a way of making energy transfer between objects easier. Problems are provided to check understanding.
