Sources Sought (SS) Title: COMET Lunaphore ACD enables multiplex sequential immunofluorescence (multiplex seqIF )-brand name ID: 75P00125Q00069-SB Post Date: September 17, 2025 Response Date: September 19, 2025 Classification Code: 6640 Laboratory Equipment and Supplies NAICS: 325413 In-Vitro Diagnostic Substance Manufacturing Introduction This is a Sources Sought notice. This is NOT a solicitation for proposals, proposal abstracts, or quotations. The purpose of this notice is to obtain information regarding the availability (foreign and domestic end products), capability of all qualified sources to perform a potential requirement. Project Summary The National Institute of Allergy and Infectious Diseases (NIAID) Tissue Analysis Core (TAC) contributes to Vaccine Research Center (VRC) mission by characterizing pathogen and immune signatures at tissue level and in cellular in vitro system to better understand natural infection and strategies of intervention and vaccines To implement current imaging workflow, NIAID is seeking a spatial immunohistochemistry technology to reveal complex interactions at tissue level for infections, vaccines, and tumor studies bypassing the limitation of the number of fluorophores with high pixel resolution using only xy resolution. Specifically, NIAID, TAC is seeking a COMET Lunaphore ACD enables multiplex sequential immunofluorescence (multiplex seqIF ). The minimum technical requirements of the COMET Lunaphore (ACD) include: Multiplex sequential immunofluorescence (multiplex seqIF ) Performs 40-plex protocols per automated run Compatible with FFPE and Frozen tissue slides Compatible with all positive charged slides (standard histology) Technology unlocked for the number of plex. preserves sample morphology and epitope integrity by gently and efficiently removing antibodies and residues from the sample. This enables samples to be reused downstream for other applications like H&E, IHC, spatial transcriptomics or sequencing Standard-label free antibodies non-conjugated and without barcoding Validated Antibody Panel for Tumor Markers Pressurized microfluidic system to reduce incubations and overall protocol times Microfluidic FFeX technology supports automated staining. The staining automation relies on 20 reservoirs for primary antibodies (20 x 2 mL microtubes) ; 4 large volume reservoirs for secondary antibodies and counterstaining (4 x 50 mL conical tubes); 7 bottles for buffers (1 x 2 L, 6 x 250 mL) 2 waste bottles (2 x 2 L) Each slide requires roughly 350 microliter of mix antibody Each run has a slide capacity of four capacity to process 20 slides per week at 20-plex protein, or 12 slides per week at 4-plex RNA and 28-plex protein, from sample preparation to registered image Automated system integrating staining, image acquisition, image preprocessing Imaging areas is 12.5 mm x 12.5 mm Staining area: 21 mm x 21 mm Integrated microscope has a Magnification 20X with a numerical aperture of 0.7 Technical resolution is 0.28 ?m / pixel Cycling fluorescence occurs through three channels TRITC, Cy5, DAPI Instrument operates with COMET Control Software Panel design is facilitated by online application generating ready-to-use protocols QC of the experiment is performed with a Viewer software. Image Analysis is optimal with the Horizon Software. Each image has a common output file format OME.TIFF supported by many image analysis tools The system weights approximately 105 kg; Dimensions are: 110.5 (W) x 63.5 (D) x 53.5 (H) cm When the left door is open, the height is 75 cm The operating Temperature is 18 25C (66 77F) which is typical of an indoor laboratory environment. The instrument should not be posed close to window for direct sunlight exposure. Extreme temperature conditions can affect the sensitive reagents used with the instrument Humidity is in the range of 20 60% Relative Humidity (non-condensing). Electrical requirements are 100 240 VA+10% grounded, 50 60Hz, 6 A, according to country. Air supply: 3-4 bars (0.3-0.4 MPa), minimum flow rate 10L/min (Compressor optionally included No vibration table is needed, and instrument can be located on a common bench area because it carries a mini-vibration surface where the slide is imaged Anticipated Period of Performance It is anticipated that an award will be made on or about September 28, 2025. Delivery of equipment will be required as soon as possible.
