What is RIN Bioanalyzer?

Table of Contents

The RNA integrity number (RIN) is a tool designed to help scientists estimate the integrity of total RNA samples. The RIN extension automatically assigns an integrity number to a eukaryote total RNA sample analyzed on the Agilent 2100 bioanalyzer.

What is a good RIN number?

A higher RIN value indicates a higher degree of RNA integrity [20]. It is generally accepted that for samples with high inter granularity, the RIN level should be about 7–8.

How RIN is calculated?

RIN is determined by the result of microcapillary electrophoretic RNA separation. Several features, including the total RNA ratio, the height of the 28S peak, the fast area ratio, and the marker height, are taken into consideration in the RIN algorithm.

How does the Bioanalyzer work?

How does the Bioanalyzer work? The bioanalyzer instrument detects biomolecules by laser-induced fluorescence. Each LabChip® contains an interconnected set of microchannels that is used for separation of nucleic acid fragments based on their size as they are driven through it electrophoretically.

How do you test RIN RNA?

To determine the RIN, the instrument software uses an algorithm that takes into account the entire electrophoretic trace of the RNA, not just the ratio of 28S and 18S rRNAs. The RIN scale ranges from 0 to 10, with 10 indicating maximum RNA integrity. The ratio of 28S and 18S rRNA peaks also is given.

What does the TapeStation measure?

Tapestation is used for quality assessment and library size for normalization prior to sequencing. library profile. This calculates the size of the library within this region and is used for normalization prior to sequencing.

How does a Bioanalyzer work for DNA?

How does TapeStation calculate concentration?

For D1000 ScreenTape and High Sensitivity D1000 ScreenTape, the concentration values are calculated using the area of the sample peak compared to the known concentration of the top marker. It is, therefore, essential that all peaks are integrated correctly in the 2200 TapeStation Analysis Software.

What is DNA integrity number?

01.05 and higher) assesses the integrity of gDNA samples and assigns the DNA Integrity Number (DIN), a numerical measure of the gDNA integrity. This value ranges from 1 to 10, where 1 indicates highly degraded gDNA and 10 represents highly intact gDNA3.
