Isoelectric focusing (IEF) is a high-resolution technique for separating proteins based on their isoelectric points, utilizing electric fields to focus molecules into sharp zones within a pH gradient. The pH gradient, created using...

Proteins, composed of amphoteric amino acids, can carry different net charges depending on the pH of their environment. The pH at which a protein has no net charge is called its isoelectric point (pI), and this varies between proteins...

Unlike SDS–PAGE, which denatures proteins, native or buffer gels maintain proteins in their functional state, allowing detection of enzymes based on biological activity. Proteins are separated by their native charge and size, and enzyme...

Two-dimensional polyacrylamide gel electrophoresis (2-D PAGE or 2-DE) is a powerful technique used in proteomics to separate complex protein mixtures based on two properties: isoelectric point (via isoelectric focusing) and molecular...

In this science activity, students will learn the steps used to create biologics by modeling the manufacturing process.

The plasma membrane is a complex structure made up of macromolecules that come together to form a fluid mosaic. In this video, we will look at the structure, properties and functions of the fluid mosaic model.

Proteins are complex macromolecules that are considered 1 of the 4 macromolecules that make up life. Proteins have many functions beyond being structural components of cells.

In this video, we explore what peptide bonds are, their crucial role in protein synthesis, and the fascinating process of their formation. Understand where peptide bonds are found in nature and their significance in biology and...

What is an amino acid? Learn about the structure, classification, types and functions of amino acids in this fun video.

What is a disulfide bond? Why are disulfide bonds so important in biochemistry? Find out these answers and more in this video!

Ribosomes are cell organelles with a peculiar structure and function. In this video, will talk about many things ribosomes, especially their roles in protein production and the differences between the types of ribosomes.

Researchers at the University of Warwick have developed innovative applications for technology in the medical field. They have used photoelastic stress analysis to determine the physical strain on artery walls caused by aneurysms,...

There are 4 main types of carbon-based molecules important to life. They are the building blocks for every living organism on this planet. In this video, I will give you a quick introduction to each type with some fun examples.

Scientists have made a significant discovery in cancer research, finding a way to turn off cancerous cells by targeting a protein called Mick. Experiments on mice have shown promising results, with previously incurable liver tumors being...

David and Agathe dive into the nutritional world of edible insects. Comparing crickets to ground beef and mealworms to salmon, they uncover surprising nutritional benefits. With the help of Alexis Chambon, they prepare insect-based...

It’s Greasy World vs. The Lunch Labbers in a high-stakes baseball game for culinary bragging rights! Freezer Burn goes nutty for Trail Mix and Lunch Lab Live welcomes some Mixed Nuts who teach us why they’re the ultimate power-packed...

The Lunch Labbers can’t keep up with Corporal Cup’s intense exercise regimen, so Fizzy and Sully the Cell teach everyone about the importance of protein to build muscle.

Hair resists decay even after death due to keratin, a structural protein. The structure and chemical composition of keratin make it difficult for organisms to break it down. Hair outlasts most other soft tissues due to the insoluble and...

A mutation is a random change in the DNA. Mutations can be neutral, which means it does not cause a change in a trait of the organism, or it could cause a beneficial or a harmful mutation. There are a few different types of mutations -...

GMO or genetically modified organisms are organisms with their DNA modified, usually by adding new or different DNA from another organism. GM crops are crops that have genes from bacteria. These genes allow the plants to either produce...

Donating blood can lead to weight loss, but this loss is not significant. As covered in this video, the average donation is 1 pint of blood, which weighs about 1 pound; so right off the bat, youre walking out of the donation center 1...

Ever wonder why bones can survive hundreds of years without decomposing? This is due to the unique composition of bone. Bone is primarily composed of a very stable protein called collagen and the mineral calcium. The association between...

Human fingernails are actually flattened versions of claws. All primates, including ancient ancestors of humans, had claws that supported their broad fingertips. The broad fingertips helped primates maintain a strong grip around objects,...

When our body sustains a wound, new cells are formed near the edges of the injury and then move down to the base of the wound. Once these cells have migrated to the center of the wound, they connect with other cells nearby. Once this...
