PERFORMANCE-BASED WORK STATEMENT

Title: Production, Distribution, and Storage of Abrine and Ricinine Reference Materials

I. Background including public health impact:

The Emergency Response Branch (ERB) of the Centers for Disease Control and

Prevention/National Center for Environmental Health/Division of Laboratory Sciences

(CDC/NCEH/DLS) is responsible for improving the detection, diagnosis, treatment, and prevention of disease from exposure to synthetic and naturally occurring chemical threat agents in order to protect the public health in the event of a chemical emergency. To achieve this end goal, ERB must develop effective and valid clinical methods for measuring chemicals and their metabolites in biological fluids, assure the quality of these methods, transfer these methods to other public health organizations including members of the Laboratory Response Network for

Chemical Threats (LRN-C), and apply these methods to incidents of suspected exposure.

ERB has been tasked with providing ongoing laboratory improvement support for the LRN-C.

To fulfill this request, ERB has identified a need for the development of reference materials for proficiency testing, calibration, and quality control programs for the detection of biomarkers for exposure chemical threat agents.

II. Project Objective:

The objectives of this task are to obtain spiked samples in biological matrices necessary for accomplishing ERB’s mission to maintain testing capabilities for toxic chemicals of interest in order to support the measurement of exposures to chemical threat agents. The proposed work will include a variety of tasks that will require planning, producing, and distributing reference materials in support of ERB’s chemical emergency preparedness and response goals.

III. Description of work (organized by Task):

The primary purpose of this project is to obtain reference materials from an ISO 17034 provider to support response activities for toxic chemicals of interest. The contractor shall produce a sizeable, homogeneous lot of a material that meets the criteria listed below. This contractor shall be make this materials available for purchase by LRN-C laboratories that participate in proficiency testing for this method at the same price-per-unit attributed to each item in the pricing table. This objective supports ERB’s mission and requires a flexible and multi-faceted approach including the key tasks provided in the Task List below.

V. Performance Matrix:

The Performance Matrix is the portion of the performance-based SOW that explains to the contractor what the Government’s expectations are, and how (and how often) deliverables or services will be monitored and evaluated. It also spells out any incentives that would encourage the contractor to exceed the performance standards. It also imposes negative incentives when the outputs/outcomes are below the performance standards.

VII. Items from CDC appropriate for task completion:

ERB will provide the contractor with a list of participating laboratories for the Abrine/Ricinine in

Urine method along with contact information for each participating laboratory. CDC will also provide ordering information to each of the participating laboratories once the contract has been awarded. If needed, LC-MS parameters for detecting both abrine and ricinine in urine may be found in the following reference: J Anal Toxicol. 2013 May ; 37(4): 237–240.

CDC can provide an adequate quantity of isotopically-labeled abrine through a Material Transfer

Agreement upon award of the contract. Any remaining material provided by CDC will be returned to CDC upon final approval of tasks 1-3 by CDC. Synthesis of any analyte is not required by this contract.

VIII. Period of Performance:

The performance period is for five years from date of award, and the overall end date is 9/30/2025.

IX. Place of Performance:

It is estimated that approximately 0% of the contract will be performed on-site at CDC facilities and 100% will be performed off-site at the contractor’s facilities. No travel is anticipated for this requirement.
