Ro/SS-A (52 kDa)

Ro/SS-A is a ribonucleoprotein particle (RNP) that is suggested to be involved in RNA quality control and the cellular stress response to UV irradiation. It is composed of uridine-rich cytoplasmic (hY) RNAs and at least four different proteins including Ro/SS-A (52 kDa), which is also known as TRIM21. DIARECT™ antigens are for further manufacturing or research use only.

Recombinant. Expressed by recombinant baculovirus (Autographa californica multiple nuclear polyhedrosis virus; AcMNPV) infection of Spodoptera frugiperda Sf9 insect cells.
