A bit more than two decades ago, the first Diablo game was released to the world. A game about a lone hero tasked with bringing down Diablo, one of the lords of Hell. This month we highlight a namesake to this hellish lord of terror, the protein DIABLO...Read more
The Cell Atlas database was just recently released with data on more than 12.000 proteins and mapping to 30 organelles. Today, the scientific findings are published in Science in "A subcellular map of the humanproteome".
The cell is a complex entity that carries out multiple functions. In order to do this, the different parts of the cells are organized in structures, called organelles. By investigating the organelles and its proteome, and to understand how the proteins vary over time and space we can truly begin to understand human biology on a detailed level...Read more
In 2017, February 28th will be the day that in Sweden is known as "Fettisdagen", (lit. "Fat Tuesday"), in other countries known as "Mardi Gras", "Faschingsdienstag" or "Shrove Tuesday". This day was originally celebrated in the Christian tradition as the last day of a three day feast to prepare for the forty day long fasting period before Easter. Today it has been popularized and in many places around the world this day is now known for its carnivals.
In Sweden together with some other northern European countries we like to eat "semlor" on Fat Tuesday...Read more
In a recent publication in Journal of Proteome Research, researchers from the Cell Profiling group of the Human Protein Atlas team present a new approach for validation of antibodies for bioimaging applications.
Antibodies are indispensible research tools, yet the scientific community has not adopted standardized procedures to validate their specificity. Here the researchers present a strategy to systematically validate antibodies for immunofluorescence applications using gene tagging.
Marie Skogs is the first author of the study.
– After a M. Sc...Read more
To prepare all the images for the Cell Atlas, released on December 4, the cells used are primed for staining and microscopy. Sample preparation is an important step when performing immunofluorescence studies. If wrongly applied it can not only cause unsuccessful detection but also generate misleading information.
The sample preparation performed by the Cell Atlas team includes cell fixation, permeabilization, and immunostaining with primary and secondary antibodies.
– The fixation is the crucial step, and different fixation protocols work better for different sets of proteins, Christian Gnann, a research engineer in the Cell Profiling group explains...Read more
