BCA

BCA is an acronym that can refer to several different organizations and concepts. This article describes three common uses: an undergraduate degree, a financial institution, and a laboratory assay.

Bachelor of Computer Applications (BCA) is an undergraduate degree in computer applications, typically lasting three years. The curriculum emphasizes programming, data structures, algorithms, databases, computer networks, software engineering, and web technologies, with project work and internships common. Graduates pursue roles in software development, systems analysis, or IT consulting, or continue with postgraduate studies such as MCA. Admission usually requires completion of secondary education with mathematics or science; entrance tests or interviews may apply in some institutes.

Bank Central Asia (BCA) is a major private bank in Indonesia, founded in 1957 and based in Jakarta. It provides consumer and corporate banking, credit cards, loans, payments, and digital banking services through KlikBCA and mobile apps. BCA operates an extensive branch and ATM network and is known for its focus on retail customers and digital innovations.

Bicinchoninic acid assay (BCA assay) is a colorimetric method for measuring protein concentration. Proteins reduce Cu2+ to Cu+, which then forms a purple complex with bicinchoninic acid that absorbs light at 562 nm. The method is relatively simple and compatible with many detergents and reducing agents, making it widely used in biochemistry and molecular biology. Standard curves with known protein concentrations are used to estimate sample amounts.
