Large business may also provide responses to this notice. The purpose of this notice is to obtain information regarding: (1) the availability and capability of qualified small business sources; (2) whether they are small businesses; HUBZone small businesses; service-disabled, veteran-owned small businesses; 8(a) small businesses; veteran-owned small businesses; woman-owned small businesses; or small disadvantaged businesses; (3) their size classification relative to the North American Industry Classification System (NAICS) code for the proposed acquisition; and (4) availability of domestic sources manufactured in the United States in sufficient and reasonably available commercial quantities and of a satisfactory quality. Your responses to the information requested will assist the Government in determining the appropriate acquisition method, including whether a set-aside is possible. An organization that is not considered a small business under the applicable NAICS code should not submit a response to this notice. This notice is issued to help determine the availability of qualified companies technically capable of meeting the Government requirement and to determine the method of acquisition. It is not to be construed as a commitment by the Government to issue a solicitation or ultimately award a contract. Responses will not be considered as proposals or quotes. No award will be made as a result of this notice. The Government will NOT be responsible for any costs incurred by the respondents to this notice. This notice is strictly for research and information purposes only. Background: The National Institutes of Health (NIH) is the nation’s leading medical research agency and the primary Federal agency whose mission is to seek fundamental knowledge about the nature and behavior of living systems and the application of that knowledge to enhance health, lengthen life, and reduce illness and disability, conducting, supporting, and making medical discoveries that improve people’s health and save lives. National Institute of Neurological Disorders and Stroke (NINDS) is one of 27 Institutes and Centers at the NIH, and its mission is to seek fundamental knowledge about the brain and nervous system and to use that knowledge to reduce the burden of neurological disease for all people. The NINDS Synaptic Transmission Section (STS) combines physiological and cell-biological approaches to understand the mechanism and dynamics of cell membrane modulation during vesicle endocytosis. Various proteins orchestrate exo- and endocytosis in living cells at the nanometer scale. These events include vesicle docking and fusion, curvature generation, endocytosis, and others. NINDS STS characterizes these proteins, especially their spatial distribution and mechanisms of action in vivo with super-resolution imaging technique, and quantify several parameters related to their performance. Then NINDS STS wants to determine how these underlying mechanisms contribute to neurodevelopmental and neurodegenerative disorders, where synaptic signaling is severely impacted. Single-molecule localization microscopy is the most advanced super-resolution fluorescence imaging technique to identify cellular components and quantify various parameters. Over more than 20 years, NINDS STS has invested efforts to understand the molecular underpinnings of the synaptic transmission process. The most critical aspect of understanding synaptic transmission and associated pathologies is to explore how the vesicle recycling process is regulated at the synapse. Previous studies from STS lab and others have shown the involvement of thousands of proteins at the presynaptic terminal to form specialized regions and facilitate vesicle fission and fusion by avoiding molecular crowding. However, the specialized arrangements have never been visualized at the nerve terminal at the single-nanometer resolution, which is the actual molecular resolution. Therefore, much of the mechanistic regulation has remained as speculative ideas. While antibodies are the preferred choice of binders to identify endogenous proteins due to their simplicity and availability, the size of each antibody corresponds to about 8nm, while two antibodies used for immunocytochemistry would be around 16nm together. The current microscope in the lab can resolve up to 1-3nm. The dual antibody staining method would create a much larger (16nm) localization error. In addition, two large antibodies would create substantial molecular crowding in the already crowded synaptic environment, thus, creating artifacts and affecting quantification. The answer to these problems lies with the nanobodies or single-domain antibody binders due to their tiny size (<3nm) and customizability. The nanobodies are produced in Camelids, such as Alpacas, and are the ideal molecules for Single-molecule localization microscopy (SMLM) using the microscope in the lab. Thus, the nanobodies will be used to perform fluorescence imaging of endogenous proteins for identifying the nanoscale structures at the cell membrane and synaptic compartment and tracking the dynamics of a variety of cell-surface proteins regulating vesicle exocytosis and endocytosis in the cells during synaptic transmission and plasticity. Moreover, the nanobodies will be used to identify the nanoscale anatomy of endocytic machinery in chromaffin cells and nerve terminals. The nanoscale organization (also called the nano anatomy) of molecules and their spatial relationship regulate key aspects of vesicle fission-fusion and, thus, synaptic transmission. It is, therefore, essential to understand the operation of multiple proteins together in the cellular context to further the research on neurodevelopmental and neurodegenerative disorders. Purpose and Objectives: The NINDS STS requires the production of nanobodies against five (5) major endocytic proteins expressed in neurons to further the research on neurodevelopmental and neurodegenerative disorders.
