Avalon GloboCare Corp. is a U.S.-based company with two distinct operating themes: early-stage life sciences commercialization and income-producing real estate. In its recent filings, the company describes research and development work around MIT-linked protein design and CAR-T related intellectual property, alongside commercialization of the KetoAir breathalyzer for ketosis monitoring. It also generates rental revenue from an income-producing property in New Jersey, which provides a separate operating cash flow stream. The business remains development-stage and capital constrained, with management explicitly warning about going concern risk and the need for additional financing.
