Huygens STED deconvolution in November issue Microscopy Today

Thursday 31 of October, 2013
In the latest November online issue of Microscopy Today, we published an article on Huygens STED deconvolution entitled: "Huygens STED Deconvolution Increases Signal-to-Noise and Resolution towards 22 nm"

To read this article we like to refer you to Microscopy Today (Volume 21:6, page 38-44)

Several customers already contributed with images to our STED Image Gallery. We would like to thank them for this!

Please contact us if you also like to be on this Gallery and/or if you want to join our Huygens Image Contest 2013

Biological gated-STED data shows resolution of 22nm achievable after Huygens STED deconvolution

Thursday 21 of February, 2013
We are very grateful to Dr. Grazvydas Lukinavicius (from the laboratory of Prof. Kai Johnsson, LIP-EPFL, Switzerland), who kindly provided us with data obtained with a Leica gated STED system showing 55nm FWHM resolution in the raw data. Keen on achieving even more, Dr. Lukinavicius used Huygens STED deconvolution to reach a blistering 22nm FWHM resolution!

New Huygens Remote Manager (HRM) 3.0 with Colocalization Analysis and Omero file transfers

Tuesday 22 of January, 2013
On Friday January 18, 2013 version 3.0 of the Huygens Remote Manager was released with many new features.

HRM is an open source web interface to Huygens Core for online, multi-user, batch deconvolution and analysis.

Whether the user is at a conference, at home or in the facility itself HRM offers access from anywhere via an internet browser. Your images can now be loaded, deconvolved, analyzed and visualized no matter where you are.

New features

In this version you'll find a new file interface to the open source OMERO server. The interface allows users to collect datasets to be deconvolved from an OMERO server and push back the deconvolution results to it. This is an initial implementation which the HRM developers are planning to extend based on users' feedback.

Secondly, you will find the possibility to use the Huygens Colocalization Analysis on your deconvolved data with great ease of use.

For a detailed list of new features please visit the official page of the HRM project.

Demo server

Feel free to test the new HRM 3.0 in the online HRM demo server.

Huygens version 4.3 released with Crosstalk Corrector

Wednesday 19 of December, 2012
Huygens version 4.3 is now released with many new improvements and a completely new optional Crosstalk Corrector.

A list of the most important improvements can be found on WhatsNew.

Crosstalk (also termed crossover or bleedthrough) can occur when acquiring a Multi Channel image. In that situation, the emission radiation of a given wavelength is detected by the wrong detector because part of the photons go through the wrong optical path inside the microscope (e.g. because the filters efficiency is not 100%). Therefore, some signal is actually recorded as coming from a certain dye when it really comes from a different one.

Crosstalk within Multi Channel images dramatically affects almost any type of data analysis, such as for example CoLocalization. In line with our aim to improve microscopic image quality and measurements, we offer from Huygens version 4.3 onwards the Crosstalk Corrector tool in the Huygens Software to correct for this imaging artifact.
More specific information of the Crosstalk Corrector can be found here

Publication on "Colocalization Analysis in Fluorescence Microscopy" describes RBNCC in Huygens

Wednesday 05 of December, 2012
Book Chapter published on "Colocalization Analysis in Fluorescence Microscopy" describes methods of colocalization analysis, and the use of replicate based noise corrected correlation (RBNCC) for improving colocalization analysis of fluorescent microscopic images. The RBNCC method has been developed by the authors of this chapter and is implemented in the Huygens Colocalization Analyzer, as part of a collaboration between the authors and SVI.

Chapter title: Colocalization Analysis in Fluorescence Microscopy
Book title: Cell Imaging Techniques
Series: Methods in Molecular Biology Volume 931, 2013, pp 97-109
Authors Dr. Jeremy Adler and Dr. Ingela Parmryd

SVI and Leica sign contract on Huygens STED deconvolution and analysis

Thursday 23 of August, 2012
Leica and SVI signed an agreement this summer enabling Leica to sell the highly effective Huygens STED deconvolution and analysis software in combination with the advanced Leica STED microscopes. Thanks to close collaboration with the Leica STED development team in Mannheim Germany, Huygens STED deconvolution allows the recovery of amazing details from the raw STED data by increasing the FWHM resolution in X, Y and Z by a factor of two (typical conditions). This resolution boost is combined with a 10-fold increase (typical conditions) in signal strength, greatly facilitating analysis of the data. With these properties, Huygens STED deconvolution makes superresolution microscopy more accessible and of greater practical value to the science community.

Huygens deconvolved image on cover Trends in Pharmacological Sciences.

Thursday 09 of August, 2012
A collaboration between the University of Pittsburgh School of Medicine, and the Massachusetts General Hospital and Harvard Medical School has led to a beautiful cover of the August issue of Trends in Pharmacological Sciences. The cover and accompanying paper, created by the authors J-P. Vilardaga, T.J. Gardella, V.L. Wehbi, and T.N. Feinstein, shows a Huygens deconvolved live early endosome. Click on this link to view the full cover.

Dr. Timothy Feinstein (Department of Pharmacology and Chemical Biology of the University of Pittsburgh School of Medicine, USA) provided us detailed information:
The image is of an early endosome labeled with PTHR-GFP (green), Vps29-YFP (blue) and beta-arrestin 1-dTomato (red), captured using a Nikon A1s spectral confocal at the Nyquist limit, based on the SVI Nyquist calculator, and deconvolved using Huygens Professional. The presentation is a reconstruction of the Huygens output that was alpha blended in Elements AR. Columns represent rotations of the endosome around the vertical axis and rows represent different combinations of color to show colocalization (red/green and blue/green) and lack of colocalization (red/blue).

See Trends in Pharmacological Sciences August issue for the paper.
