Zusammenfassung:An object of the present application is to provide new anti-Fc epsilon R-antibodies which enable B cells to be identified at a specific differentiation stage as well enabling the different degrees of atopy and Fc epsilon -receptor expression to be defined as a result by the showing that Fc epsilon R is a B cell specific phenotype marker, the expression of which is strictly correlated with the differentiation stage of B cells, especially with the isotype switching in B cells. Therefore, Fc epsilon R positive B cells can be recognized by detection with the new antibodies of the expressed Fc epsilon R, e.g. the expressed Fc epsilon R in supernatant or biological fluid having a molecular weight of about 25 Kd, and the use thereof in an ELISA. An further object are hybrid cell lines producing these antibodies.
