Fibrillarin (C13C3) Rabbit mAb (Alexa Fluor® 647 Conjugate) detects endogenous levels of total fibrillarin protein.

Monoclonal antibody is produced by immunizing animals with a synthetic peptide surrounding Thr298 of human fibrillarin.

This Cell Signaling Technology antibody is conjugated to Alexa Fluor® 647 fluorescent dye and tested in-house for direct immunofluorescent analysis in human cells. The antibody is expected to exhibit the same species cross-reactivity as the unconjugated Fibrillarin (C13C3) Rabbit mAb #2639.

Fibrillarin is a 2'-O-methyltransferase located in fibrillar regions and Cajal bodies of the nucleolus, where RNA transcription and pre-RNA processing take place (1,2). Fibrillarin associates with several other structural proteins as well as box C/D snoRNA to form a complex that functions in pre-rRNA processing, pre-rRNA methylation, and ribosome assembly. This complex catalyzes site-specific 2'-O-ribose methylation of targeted nucleotides within the rRNA sequence (3,4). The sequence, structure, and function of fibrillarin are highly conserved and fibrillarin gene expression is essential for early embryonic development (5).
