correct the fluorescence EEM for inner filter effects, thus facilitating truly quantitative and highly selectable molecular fingerprints. A-TEEM fingerprints of very similar components are often unique, enabling quantitative analysis of responsive components to ppb levels. This makes it a natural fit for the characterization of many relevant bio pharmaceutical products such as Vaccines, Insulin, Viral Vectors (AAVs), Antibody-Drug Conjugates (ADCs), Cell Media, Exosomes, CRISPr/CAS9, and more. As a spectroscopic tool, A-TEEM can be deployed for process analytics, used to monitor bioprocesses, or screen for batch-to-batch variance across a variety of relevant biomolecules. Putting a sample in a cuvette is often the only preparation needed for measurement. For some quantitative measurements, sample dilution may be required. Speaker Linda Kidder Yarlott, Life Sciences Business Development Manager, HORIBA Scientific Membership Committee Meeting 3:30 pm - 5:30 pm, Room 14A Career Development Center Workshop Negotiation for Biophysicists: Negotiation Strategies and Tactics and Evaluating a Job Offer 4:00 pm - 5:00 pm, Room 16B We will address strategies and tactics to evaluate a job offer and to nego tiate for what you are worth in the employment marketplace, including postdoc and faculty roles.
