Job Information

Sanofi Group Research Associate II in La Jolla, California

Research Associate

Synthorx has advanced a revolutionary technology that expands the genetic alphabet to drive the sitespecific

incorporation of multiple non-natural amino acids into proteins of any size, and to manufacture

these improved proteins at scale. This technology opens-up opportunities to make novel protein

therapeutics to previously difficult to drug targets. We are hiring a Research Associate to work with our

team to develop new assays that will support the functional profiling and safety evaluation of Synthorx

therapeutic agents. He/she will implement a variety of cellular and ligand binding assays to monitor the in

vitro and ex vivo pharmacology of large molecule (biologic) leads at T, B and natural killer (NK) cell

subsets. The candidate will also play a key role in the design and implementation of read-outs for T, B

and NK cell function and immune toxicity (cytokine release, vascular leakage), including samples from in

vivo studies. He/she will actively scout the pre-clinical and clinical literature, and patent records, in search

for example molecules and study systems to test the pharmacological and safety properties of current

and future targets in the Synthorx portfolio.

Key Responsibilities:

• Develop flow cytometry panel to support PD (pharmacodynamics) analysis for in vivo and in vitro

pharmacology, and perform sample analysis with flow cytometry software.

• Develop appropriate immunoassays to support PK (pharmacokinetic) analysis of large molecule

pharmacology in in vivo models and perform the sample analysis.

• Develop cell-based potency assays to support the lead compound selection and pre-clinical


• Culture and maintain cell lines and primary cells, for cell-based assays, manage mammalian cell

stock inventory.

• Coordinate with other lab members day-to-day lab activities including equipment maintenance,

reagent orders, restocking consumables, etc.

• Develop appropriate assays to support analysis of large molecule pharmacology in in vivo


• Effectively work and communicate with group members and contract research organizations, in a

dynamic and fast paced environment to accomplish goals.

• Prepare and present power point summary data slides.


• BS in biomedical sciences and 2 years of lab experience or related field; OR MS in biomedical

sciences or related field.

• Proficiency in flow cytometry and immune cell isolation and characterization.

• Proficiency in ELISA and MSD.

• Experience in cell culture and aseptic technique is required.

• Experience with multiparametric flow cytometry is required.

• Experience with handling human tissue specimens (mostly blood).

• Experience with cell sorting is a plus.

• Experience with animal models is a plus.

• Familiarity with BSL-2 protocols and best-practices.

• Experience with tumor-dissociation and analysis of tumor infiltrating cells.
