Slingshot Biosciences is an Emeryville, California biotechnology company that engineers synthetic cell mimics — hydrogel-based particles that behave like real cells — as reproducible reference materials and controls for flow cytometry, spectral unmixing, immunophenotyping, cell and gene therapy potency assays, and instrument standardization. Its product families include TruCytes biomarker controls, ViaComp cell health controls, FlowCytes and ScatterBridge calibration controls, SpectraComp compensation and unmixing controls, QuantCytes quantitation controls and StimCytes functional controls. The company sells direct through a Shopify-backed storefront and publishes an unusually complete agent-facing surface for a life-sciences vendor: an llms.txt, an RFC 9727 /.well-known/api-catalog naming its Shopify Storefront GraphQL and Sanity Content Lake GROQ endpoints, content negotiation that serves markdown twins of every canonical page to agents that send Accept: text/markdown, and a live Shopify Storefront MCP server.
