World Down Syndrome Day 2021

Today is the 10th Annual World Down Syndrome Day (WDSD). This date is observed by the United Nations as a global awareness day to celebrate the lives of people with Down syndrome.

 

International Day of Women and Girls in Science 2021

Today is the 6th International Day of Women and Girls in Science. On this day, which is implemented by UNESCO and UN Women – the United Nations entity dedicated to gender equality and the empowerment of women – we recognise the critical role of women and girls in science and technology.

RNA Isolation in 7 Minutes – Go!

Total RNA is the starting point for a plethora of applications that can help to answer questions about the mechanisms of human and plant disease, gene regulation, embryonic development, transcriptional responses to treatments and stimuli, and more. Regardless of the application in hand – whether it be cDNA synthesis for reverse-transcription PCR, RNA-seq, northern blotting or otherwise, sufficient amounts of high-quality RNA will be a requisite.

DNA Isolation From Low Input Samples

Whole genome sequencing and related ‘omics’ technologies have paved the way for many new possibilities within basic and clinical research, and they are becoming an integral part of the personalised medicine era by identifying individual genotypes that can direct diagnosis and therapy.

Besides a sequencing instrument, reagents and personnel who can translate the sequencing reads into workable data, the only, albeit, most important prerequisite is a sufficient amount of high-quality genomic DNA.

To Gate or Not to Gate?

Flow cytometry is one of the most intensely used techniques in immunology that creates big amount of data in short amount of time. It is possible to obtain information on cell surface markers, cellular processes such as apoptosis, and signaling pathways and much more.

To get a reliable result in flow cytometry, proper controls for accurate gating is essential. Gating means to sequester specific group of cells. This is generally a manual step performed during and after data acquisition. Even though gating can be straightforward for substantial cell groups such as CD4+ cells in PMBC samples; it can be tricky when it comes to less obvious populations, for cells that have transient marker expression or small cell populations.

In this blogpost, we want to give some tips on how to use flow cytometry controls to get more successful gating and subsequently more consistent data.
