Bence Jones re·ac·tion

(bents jōnz),

the classic means of identifying Bence Jones protein, which precipitates when urine (from patients with this type of proteinuria) is gradually warmed to 45-70°C and redissolves when the urine is heated to near boiling; as the specimen cools, the Bence Jones protein precipitates in the indicated range of temperature and redissolves as the temperature of the specimen becomes less than 30-35°C.

Bence Jones reaction

The classic method for identifying the 22–24-kD monoclonal Bence Jones protein (BJP), which is based on precipitation of BJP from urine at 45–70º C (it goes into solution at temperatures above or below this range). While the Bence Jones reaction confirms the presence of multiple myeloma, Waldenström’s macroglobulinemia, CLL and amyloidosis, it is inelegant; serum-free light-chain assays have greater diagnostic utility than urine tests.
