Attachment A - Estimated Volumes.xlsx

This file is an estimated annual volumes spreadsheet for immunohistochemistry (IHC) and in-situ hybridization (ISH) products and supplies supporting GSA contract 36C25226Q0212. The spreadsheet itemizes estimated annual procurement volumes across two locations: Hines and Milwaukee, representing anticipated demand for a comprehensive range of diagnostic reagents and consumables.

The products listed include primary antibodies for pathology diagnostics (CD markers, cytokeratins, tumor markers such as PSA, TTF1, and p53), detection kits (DAB, Red Detection, and Dual Detection systems totaling approximately 9,200 tests annually), epitope retrieval solutions in both low and high pH formulations, and laboratory consumables such as covertiles, mixing stations, open containers, enzyme pretreatment solutions, and probe cleaning reagents. Notable high-volume items include SOX 10 antibodies (1,880 annual units combined), HPp ASR (1,679 units from Hines), CKAE1/AE3 (598 units from Hines), Brown Kit reagents (10,700 units), and DAB Detection kits (6,800 tests). Additional supplies encompass printer labels (9,000 units), aspirating probe cleaning (1,015 units from Hines), and various container sizes. This estimated demand establishes the baseline for contractor fulfillment under the IDIQ contract with a guaranteed minimum of $250,000 and contract maximum of $2,500,000 across all performance periods.
