Single-Sole Source Determination
One major research project of the Hattar Lab is to determine the transcription profiles of cell types involved in Intrinsically photosensitive retinal ganglion cells (ipRGCs)-brain neural circuits. We, and many other labs, have been using probes and reagents from RNAscope Product line to perform systematic RNA in situ hybridization experiments to visualize the RNA localization within cells. Since ACD Bio-techne is the sole supplier for RNAscope Product line, this is a sole source procurement.

I hereby determine that the RNAScope in situ hybridization probes and reagent kits listed herein is available from only one source, and competition is precluded for the reasons indicated below. There are no substitutes available.
Background/Description of Requirement
      1. Salient characteristics
    1. RNAscope® is a novel proprietary RNA in situ hybridization (ISH) method that enables routine detection and visualization of virtually any expressed gene in any tissue such as FFPE, Fresh frozen and fixed-frozen tissue.
    2. RNAscope® was designed to amplify target-specific signal without also amplifying the background signal, resulting in marked improvement in signal-to-noise ratio.This is accomplished by ACD’s patented double Z-probe design for in situ hybridization, where two independent probes (a double Z probe pair) are required to hybridize in tandem to the target sequence in order for signal amplification to occur. Since it is highly unlikely that two independent probes will hybridize to a nonspecific target right next to each other, this design concept ensures highly selective amplification of target-specific signals, therefore improving both sensitivity and specificity.
    3. Based on its patented probe design, RNAscope enables as much as 400-fold improvement over conventional RNA ISH, resulting in high detection sensitivity.
    4. Technology enables in situ detection of RNA molecules as small as 300bp, including degraded mRNA.
    5. ISH nature enables preservation of cellular and molecular context
