q22

Q22 is an alphanumeric designation that appears in a variety of unrelated contexts. Depending on the field, it can refer to a transit route, a product model, or a catalog code.

In transportation, Q22 is used by some public transit authorities to designate a specific bus or rail line. The route, operator, and schedule vary by city and over time, so consultation of local transit resources is required to determine current service.

In technology and consumer electronics, Q22 frequently designates a model or part number assigned by manufacturers. Different brands may use the same code for entirely different products, so product data sheets or retailer listings are needed to identify features.

In other domains, Q22 may appear as an internal project name, equipment tag, or production code in media, manufacturing, or research settings. It is not a universally standardized term with a single, fixed meaning.

In genetics and biology, standard nomenclature rarely uses "Q22" as a formal label; chromosome designations use chromosomal location such as 22q11.2 for certain human disorders, and "Q" typically marks the long arm of a chromosome (denoted "q"), not a standalone "Q22".
