**Role Responsibilities** High throughput (HTP) protein purification scientist. Responsibilities include operating automated protein production and liquid handling equipment, conducting high throughput, small-scale protein purification and analysis, managing protein inventories, and maintaining a database to support departmental needs for antibody production and characterization. Work directly with other scientists focusing on high throughput molecular cloning and mammalian cell transfection/expression. Specific responsibilities include: Manage protein purification and characterization for hundreds of therapeutic candidates. Develop, optimize and perform small-scale, robotic purification of proteins using Protein A chromatography. Develop, optimize and perform small-scale, robotic buffer exchange purification on weekly basis. Develop, optimize and perform small-scale robotic protein characterization. Maintain and run high pressure liquid chromatography (HPLC) instruments. Perform robotic sample distribution to end users, including transfer to multiple small vials and adjustment of protein concentration. Upload purification and characterization data into departmental sample database daily. Develop and manage sample/request database. Interface with requestor for sample and data transfer. Perform automated protein assays (enzyme linked immunosorbent assay - ELISA or equivalent). Manage protein purification laboratory: Prepare and maintain inventories of protein purification chromatography apparatus.

**Sunshine Act**

Pfizer reports payments and other transfers of value to health care providers as required by federal and state transparency laws and implementing regulations. These laws and regulations require Pfizer to provide government agencies with information such as a health care provider's name, address and the type of payments or other value received, generally for public disclosure. Subject to further legal review and statutory or regulatory clarification, which Pfizer intends to pursue, reimbursement of recruiting expenses for licensed physicians may constitute a reportable transfer of value under the federal transparency law commonly known as the Sunshine Act.
