provide a powerful tool for investigating the function of this protein.

Autoantibodies against the snRNP proteins B and B' are a common feature
of the autoimmune disease systemic lupus erythematosus [1]. We screened a
Agtl 1 cDNA expression library, made from polyA+ RNA from HL-60 cells, with
a monoclonal antibody specific for B and B'. This monoclonal antibody was ob-
tained from a fusion between spleen cells of an MRL/lpr mouse and sp2/0 cells.
Screening of 700000 clones resulted in three positive clones (clone 5, 9 and 16),
which reacted also with a second monoclonal antibody specific for B and B' and
with a panel of human anti-B/B' sera, obtained from patients with autoimmune
diseases.
To characterize ^-galactosidase fusion proteins, clone 5, 9 and 16 were in-
troduced in a lysogenic host. All three clones produced fusion proteins with a mo-
