Martin started off his early career investigating contraceptive vaccines. He eventually gained his PhD in nanotoxicology from Edinburgh Napier University. A return to reproductive biology followed working with the MRC in endometrial pathology research. Following a brief detour into global pharmaceuticals, Martin joined the Bitesize Bio team and set up the Microscopy and Imaging Channel. Now a completely free-range human, Martin runs his own arts and crafts business creating award-winning hand carved slate and stone pieces. Martin is still very much involved in Bitesize Bio and is a regular contributor to the magazine. You can find out more about his stone carving on his Facebook page (www.facebook.com/hatchburnandcarve), or visit his website.

Tissue Processing For Histology: What Exactly Happens?

When preparing a sample (or multiple samples) for histology microscopy, there are multiple steps required. We’ve covered these steps in brief in a previous article on How Histology Slides are Prepared, but this article will focus on one particular procedure that needs to take place between tissue fixation and the embedding/sectioning of paraffin blocks: tissue…

Microscope Finder Slides: Their History, Development, and Use

Have you ever been looking through a box of slides and found something that you want to image or look at later, or even show to one of your colleagues or supervisor? Finding that exact spot on the slide at a later date can prove to be difficult- using a marker pen on the coverslip…

Scientific Cyber Fraud: Nobody Move—We’re Taking Over This Journal!

Keeping up to date with the scientific literature is a large part of the work-load of any researcher. Love it or loathe it, this means of sharing research findings with the larger scientific community is still the way in which most of us inform ourselves of the latest findings in our fields of research, or…

Microscope Cameras: From SLR to CMOS Devices

Photography has undergone great improvements in the last few decades. In times gone past, photographic film was used. Now most researchers use digital means to capture their images. But not all digital cameras are the same. For optimal results you need to know the different types of microscope cameras and how they work. Before the…

Just This Moment. Introducing the Science Behind Mindfulness and Meditation

How often have you looked at slides down the microscope and your thoughts have been miles away? Have you ever been sitting at the bench pipetting and preparing a PCR and wondered if you had really added your forward primer to all your samples (I’ll put my hand up to this one!)? Or spent time…

Microscope Condensers: Don’t Forget Those Parts Underneath!

When you first start out using a microscope, you might only adjust the eye pieces, objectives, and the focus controls. However, you shouldn’t overlook the microscope condensers as they are an important part of the whole optical system of a microscope.

The Why and How of Oil Immersion Microscopy

Do you know why immersion oil and objectives are used for high power magnification? Do you know how to use an immersion objective correctly? Then review with me the why and how of immersion objectives. The quality of your image depends on your Numerical Aperture (NA) and resolution. To very briefly recap, NA relates to…

Vitamin H and Egg White: Streptavidin-Biotin for Immunohistochemistry

If you want to make molecules stick together you need to know about streptavidin/biotin. This article follows on from Mike’s article looking at ‘sandwich’ and ‘amplification’ methods of immunohistochemistry (IHC) and covers how streptavidin-biotin works in IHC, including protocols. Streptavidin-Biotin What is it? Avidin is a natural biotin-binding protein found in egg whites. Streptavidin is similar…

PIER, HIER and Mannich: Antigen Retrieval in Immunohistochemistry

When you fix your tissue samples with paraformaldehyde (PFA) the proteins in your sample become covalently cross-linked. This is good to preserve the ‘architecture’ of your tissue sample. However, this cross-linking can become a problem when you carry out immunohistochemistry (IHC). Cross-linking can ‘mask’ or hide your antigens-of-interest and make them ‘invisible’ to your IHC…

Looking good! A Guide to Adjusting and Maintaining Microscope Eyepieces

The magnification and viewing of samples using a microscope relies on both the objectives and the eyepieces working harmoniously together. If you buy a ready-to-use microscope, then the objectives and the eyepieces which are fitted as standard will be designed to complement each other. On the other hand, if you are designing and building a…

Taken for Granted: Position and Setup of Your Microscope

Working at a microscope for long periods of time is a daily feature of many individuals, both those performing research and those undertaking point-of-care microscopy. And while I say ‘taken for granted’, over the years of working in and managing microscope facilities, it quickly became clear that the position of the microscope, user position and…

I Can See (See Dee)! CCD and CMOS Cameras for Micoscopy

Two different sensors are generally used in cameras for microscopy: Charge Coupled Devices (CCD) or Complementary Metal Oxide Semiconductors (CMOS or sCMOS). Although there are a number of similarities between the two sensors, differences in the way they function can have an effect on image capture time as well as signal-to-noise ratio. Let’s take a…

An Objective View: What do These Abbreviations Mean on Microscope Objectives?

In one of the previous articles from the Microscopy and Imaging Channel, we took a look at ‘that other number’ which you’ll find on a microscope objective: namely numerical aperture. The information you’ll find on objectives doesn’t stop there though- another piece of information to be found on the barrel of the objective is the…

Dots, Probes and Proteins: Fluorescent Labels for Microscopy and Imaging

If you remember from one of my previous articles (if not, you can read it here!), we introduced ‘fluorophores’. These are basically substances (natural or synthetic) which have the ability to absorb light at a low wavelength and re-emit at a higher wavelength. In other words- they fluoresce! In this article, I’ll introduce the three…

Light Through Crystals: What Exactly is Differential Interference Contrast Microscopy?

Although his name could fit in easily to the early 1980’s Hip-Hop Scene, Jerzy Nomarski (or ‘George’) was actually a Polish physicist with an interest in optical theory. Born in 1919, he eventually became a member of the Polish Resistance fighting in the Second World War. He was captured by enemy forces and held as…

Catching Waves: What a Microscopist Ought to Know About Phase Contrast

Phase contrast microscopy is a light microscopy technique which is primarily used to visualise live cells. Using various filters and condensers, the image produced by phase contrast allows us to see greater detail in live cells and can highlight aspects such as intracellular structures. Keep your cells alive! The best way to view cells is…

This One’s Upside Down! Inverted and Stereo Microscopes in Bioscience Laboratories

Most of the microscopes you will encounter in your laboratories will be ‘upright’. In other words, they are assembled (from top to bottom) in the order of; eyepieces, objectives (on revolving nosepiece), stage, sub-stage condenser, diaphragm and base. However, there are two other types of light microscopes you will perhaps encounter (and use) and it…
