Fibrillarin, ID (FBL, 34kD Nucleolar Scleroderma Antigen, rRNA 2'-O-methyltransferase fibrillarin, FLRN, FIB1, Nop1p, RNU3IP1)
Description:
FBL is a component of a nucleolar small nuclear ribonucleoprotein (snRNP) particle thought to participate in the first step in processing preribosomal RNA. It is associated with the U3, U8, and U13 small nuclear RNAs and is located in the dense fibrillar component (DFC) of the nucleolus. This protein contains an N-terminal repetitive domain that is rich in glycine and arginine residues, like fibrillarins in other species. Its central region resembles an RNA-binding domain and contains an RNP consensus sequence. Antisera from approximately 8% of humans with the autoimmune disease scleroderma recognize fibrillarin.

Applications:
Suitable for use in ELISA and Western Blot. Other applications not tested.

Recommended Dilution:
ELISA: 1:1,000
Western Blot: 1:50-1:100
Optimal dilutions to be determined by the researcher.
