Unlock the secrets of your samples at Refeyn’s Mass Photometry Workshop! Refeyn will present a seminar on mass photometry at this event, along with a live demonstration of the TwoMP mass photometer. Attendees are invited to bring their own samples for analysis (see details below). The presentation and demo will be delivered by:

Sample requirements
Sample Limit:
3-4x samples per person
Mass Range:
30 kDa to 5 MDa
Sample Concentration:
Ideally, stock solutions should be at a concentration of 1 μM or higher (for proteins & biomolecules) or 500 ng/ μL or higher (for nucleic acids) as prior to measurement samples will be diluted to 5-20 nM (proteins) or 20-50 ng (nucleic acids).
Sample volume:
≥ 10 µL for stock solutions, but the volume per measurement will be 10-20 µL
Buffer Requirements:
Your preferred buffer can be used for the measurement of your samples. Please provide us with 5 mL of your buffer for dilution purposes, equilibrated to room temperature (RT). In the event your buffer contains any of the following “additives” we kindly ask you to have buffer without these additions present (also 5 mL):
- Urea or guanidium hydrochloride (Gnd-HCl)
- Glycerol, sucrose, or other sugars (only if above 10 %)
- Detergents
- Inorganic solvents (e.g. DMSO only if above 5-10 %)
