Gas Chromatography

In this article, we bring together resources from the across the site on gas chromatography, how it works, its pairing with downstream techniques and what its applications are.

Introducing the Antibody

Antibodies are a vital part of the immune system, playing a key role in our ability to fight infection and in the efficacy of vaccinations. However, that’s not where their utility ends. Find out about what antibodies are, where they come from, how they function and how science is putting them to work in the laboratory.

Taking Cultured Meat to the Next Level

In a study published in Metabolic Engineering, bovine cells were engineered to endogenously produce phytoene, lycopene and β-carotene. We recently had the pleasure of speaking to Andrew Stout, lead author of the study, to learn how these cells were created and explore some of the benefits of engineering in the abilities to produce additional nutrients.

Single-Cell, "Multi-Omics" Analysis Uncovers a New Stage in Immune Cell Formation

A research team from The Walter and Eliza Hall Institute has adopted a single-cell, multi-omics approach to explore this question, focusing particularly on T and B lymphocyte formation. They discovered a new stage in lymphocyte development, information which the researchers say could "enrich future studies of the immune system". We wanted to know more.

Teach Me in 10 – An Introduction to ICP-OES With Ross Ashdown

In this installment of Teach Me in 10, we're joined by Ross Ashdown, who talks us through the basic concepts of inductively coupled plasma-optical emission spectrometry, or ICP-OES.

T-Cell Responses to SARS-CoV-2 Still Present Six Months After Initial Infection

A recent preprint study, published in bioRxiv, demonstrates robust T-cell responses to SARS-CoV-2 viral peptides six months after initial infection in all participants following asymptomatic, mild or moderate COVID-19.

Using Analytical Chemistry To Put an End to Corked Wine

The sound when the cork “pops” out of the bottle is satisfying isn’t it? But what disappointment if at that very first sip the off flavors of a faulty wine hit your tongue. In this article we are going to focus on cork taint, what it is, how analysts detect it and ways to prevent it.

Leading the Charge in the Cryo-EM Resolution Revolution

See how cryo-EM advances are changing scientific research, particularly in cell and drug discovery studies, and the role that precision instruments are playing in this.

Teach Me in 10 – An Introduction to ICP-MS With Abe Gutierrez and Ed McCurdy

In this installment of Teach Me in 10, we're joined by Abe Gutierrez and Ed McCurdy, who provide an eloquent introduction to inductively coupled plasma mass spectrometry, or ICP-MS.

Opinionated Science Episode 15: COVID-19 and the Brain: Investigating the “Silent Wave”

On this episode, the team will discuss how the SARS-CoV-2 virus affects our brain. This podcast will untangle the disparate effects involved, covering everything from a subdued sense of smell to serious brain inflammation and damage.
