January’s ‘Paper(s) of the Month’ come from the Gibson Group at the University of Warwick, a research group led by Dr Matt Gibson.

Matt and his group work at the interface of the organic and polymer chemistries with the life sciences, making use of modern polymer and organic methods to synthesise nano materials for various applications, including regenerative medicine, infectious disease and biotechnology.

Inspired by the evolutionary survival methods of polar region species, such as freeze avoidance using antifreeze (glyco)proteins (AFPs), the team has been working on the design and synthesis of polymer-based AFP mimics as novel new cryoprotectants for cell cryopreservation. They hope this will ultimately improve the availability of transplantable materials for regenerative medicine.

Welcome back everybody, and a Happy New Year!

At Linkam we have set ourselves a couple of resolutions for the year 2016.

Firstly, we will seek more feedback regarding our stages, so we can continue to refine them to best meet our users’ wants and needs. We hope this is something you might be able to help us with and look forward to talking with you all a bit more over the coming year.

Secondly, we will release a whole range of exciting new products, including our new LINK64 software. 

For updates keep an eye on the website, and on our Twitter and LinkedInpages. Or, if you want to come and see us in person, you can find details of the trade shows Linkam, and our distributors, will be attending in 2016 over on our events page.

We recently discovered an amazing liquid crystal photo gallery, with a collection of microphotographs all taken using a Linkam LTS350 stage (predecessor to the LTS420).

The photos were taken by Dr Vance Williams, an Associate Professor at Simon Fraser University in British Columbia, Canada, who is Principal Investigator in an organic materials chemistry group called the Williams Research Group.

November's Paper of the Month is now live! 

It comes from a team at the University of Alberta, who have been studying how intracellular ice formation during cryopreservation of cells is affected by the degree of supercooling and the cell volume.

In this study the number of human umbilical vein endothelial cells (HUVECs) undergoing intracellular ice formation at different degrees of supercooling were examined on a cryostage. Intracellular freezing can be detected by the darkening of cells. Cell survival after thawing was determined using a membrane integrity assay. In the picture above, the cells with intact membranes can be seen in green and the cells with damaged membranes can be seen in red.

A team from the Hofmann Lab at the University of California, Santa Barbara, are studying the impacts of ocean acidification in calcifying marine invertebrates such as the pteropod Limacina helicina antarctica (pictured).

The team are based at the McCurdo research station in Antarctica, and have been using the Linkam PE120 stage to observe samples both at ambient temperature and at -5°C.

Freeze Drying Training Course

We are pleased to be involved with the Freeze Drying Training Course ‘Lyophilisation: Practical Applications Utilising Latest Equipment’ at the Hooke College of Applied Sciences, running from 3rd-5th November.

This course covers aspects of freeze drying as it relates to the pharmaceutical, biological and food industries. These topics will first be discussed in a classroom setting and then put into practise in an onsite laboratory. Attendees will get hands-on experience with the Linkam FDCS196 freeze-drying cryo-stage.

Details and registration

The Linkam FDCS196 freeze drying system provides the ability to quickly and accurately determine collapse and eutectic temperature and intricately investigate freeze dried structure of complex samples.

Linkam Scientific introduce students to the CMS196 cryo-CLEM stage at the Francis Crick Institute

Towards the end of September we attended the UK’s first Correlative Light and Electron Microscopy (CLEM) interactive workshop. This was held at the prestigious Francis Crick Institute, in London, and will take place in alternate years with the European EMBO CLEM course in Bristol.

The course was fully booked with eight participants from eight different institutes in the UK working in pairs throughout the week to learn different CLEM workflows. The Linkam CMS196 Cryo-Correlative stage was used during the workshop so students could get practical experience of the system and see how it fits into the Cryo-CLEM workflow.

Above is a picture of mouse embryonic fibroblast (MEF) cells, prepared by PhD student Patricia Goggin and captured by Linkam's Michael Schwertner during the ‘correlative cryo-fluorescence leading to cryo-electron tomography or cryo soft x-ray tomography’ practical. This cryofluorescence image shows the cell nuclei in blue, mitochondria in green and filamentous actin in red. 

We had a great time showing off some of the features of our cyro-CLEM stage whilst also continuing to learn about some of its applications, and our thanks go to everyone involved, especially Dr Marie-Charlotte Domart, Dr Raffa Carzaniga, Dr Lucy Collinson and Dr Paul Verkade.

Linkam supporting Correlative Light and Electron Microscopy Workshop at Francis Crick Institute

Linkam will be supporting the first UK hands-on workshop on ‘Correlative Light and Electron Microscopy', being held at the Francis Crick Institute in London from September 21st to 25th.

The workshop is organised by Raffa Carzaniga, Lucy Collinson and Paul Verkade, and will take place in alternate years with the European EMBO CLEM course in Bristol (next course in July 2016), enabling us to train more of the UK community in a wide range of CLEM techniques. The workshop will include detailed hands-on tutorials for 8-10 participants organised into groups of 2 people per tutor to maximise contact time, covering high pressure freezing and freeze substitution; preservation of fluorescence in-resin for integrated microscopy; plunge freezing, cryofluorescence and cryoEM; Tokuyasu cryosectioning and immunolabelling for correlative experiments; and 3D CLEM using Serial Block Face SEM.

The Linkam CMS196 Cryo Correlative stage will be used during the workshop so students will be able to get practical experience of the system and see how it fits into the Cryo-CLEM workflow.
