We now offer BSL2+ sorting!

We are now able to run a wider variety of BSL2 samples on our Aria3 and Bigfoot sorters. Per Universal Precautions: All primary human samples will be considered BSL2 samples.

Prior to being able to run such samples, please complete the following questionnaire:
BSL2+ PI Questionnaire - To be filled out by the PI of any lab that wishes to sort BSL2 samples.
Our BSL2+ sorting policies can be found here. Please review them prior to sorting BSL2 samples with us.

The Amendment form can be found here.

Note:  High fluid pressures required in high-speed cell sorters can generate large amounts of aerosols of various and undefined droplet sizes during instrument failures, for instance, when a partial clog in the nozzle causes a deflection in the fluid stream that is hitting a hard surface, e.g., the waste catcher. 
The HSCI-CRM flow core provides sorters with varied levels of aerosol mitigation to protect instrument operators and anyone in the vicinity of the sorter. The level of containment is based on risk level.
The most basic containment is provided by enclosing the stream within a sealed chamber, and the sort receptacles which are connected to this closed chamber have no gaps that would allow aerosols to escape. This is containment is suitable for cells that pose a very low risk. This might include murine cells that are uninfected, or fixed samples.
For samples that are BSL1, for example BSL1 human cell lines, or cells infected with non-replicating viruses for transfection, the closed chamber has a vacuum applied via an Aerosol Management System (AMS) which actively removes any stray aerosols. The sorter is enclosed in a biosafety cabinet for additional operator safety.
For BSL2 samples – any primary human cells, non-human primate cells, or infected samples – the sorter is enclosed in a biosafety cabinet with an AMS; it has also been placed in a separate room to limit access while the sort is happening.

Biosafety Agreement – For all new users. Please complete and submit this form if you intend to use our core facility. This needs to be submitted to us before scheduling any time.

Human Sort Document – For anybody bringing live, tested, uninfected human samples (non-BSL2). You must either bring this form every time you bring live human cells, or link to fill out the online form here.
Anybody working with live human cells (non-BSL2 cell lines) MUST also bring documentation stating that the cells have been tested and found negative for HIV, HepB, and HepC and are otherwise non-infectious samples.

BSL2+ PI Questionnaire - To be filled out by the PI of anyone who wishes to sort BSL2 samples.
