The BioMicro Center hosts several instruments to assist in quantifying nucleic acids and determining their size and purity. All samples submitted to the BioMicro Center for assisted services are routinely assayed on these instruments and they are used to monitor success of library production steps. Quality control is also a stand alone service available to researchers.

The Advanced Analytical Fragment Analyzer (FA) is a highly efficient and accurate fluorescence-based electrophoresis instrument used to size and quantify DNA and RNA. It is faster and more cost effective than the BioAnalyzer2100, and can handle unsupervised runs of up to 192 samples. Each run takes ~60 minutes and 2 μL of sample. Users may submit any volume of sample with the expectation that if there is less than 2 μL, the samples will be diluted. To save money and submit a larger quantity of samples, users may come into the BMC and obtain a special 96 well plate or plates. For mass submission, 2 μL must be put into each sample well row by row. There is a way to submit rows in iLabs, but please remember to come and get special plates from the BMC to do mass submission.
The Fragment analyzer was purchased in 2012 and upgraded to handle 48 samples in a batch in 2017. Fragment analyzer reports a "RIN eQuivalent Number (RQN) instead of RIN.

The FEMTO Pulse is a brand new instrument that provides a remarkable upgrade over the existing AATI Fragment Analyzer and Agilent BioAnalyzer technologies that have been available for many years. While still an instrument to analyze the lengths of nucleic acids, the FEMTO Pulse adds a pulse filed generator to allow the separation and characterization of significantly longer molecules, out to 200,000 base pairs. Additionally, the FEMTO pulse has significantly improved optics that allow approximately two orders of magnitude of additional sensitivity. Where the AATI fragment analyzer bottoms out a sensitivity of 2-3pg/ul, the FEMTO pulse has nearly 100x improved sensitivity which may enable this instrument to directly observe molecular reactions without the need for amplification or modification with radioactive nucleotides.
The FEMTO Pulse runs 12 samples at a time using 2ul of material. Each run takes ~90 minutes to run. It is *not* a replacement for the Fragment Analyzer and is optimized for very low inputs or very long samples.
The Agilent 2100 BioAnalyzer is a microfluidics device that preforms size fractionation and quantification of small samples of DNA, RNA, or Protein. In addition, the BioAnalyzer is able to preform flow cytometry on small numbers of cells. Samples can be run on the BioAnalyzer either by individual scientists or by the BioMicro Center.
Samples can also be run by individual users on the BioAnalyzer after a user has received training by emailing bmcwetlab@mit.edu (Core Labs only please). This service will be discontinued if we find the machine is abused. Once you are trained in the use of the BioAnalyzer you are welcome to sign up for usage on ilabs.
