Rabbit anti Human fibrillarin antibody recognizes the rRNA 2′-O-methyltransferase fibrillarin, also known as 34 kDa nucleolar scleroderma antigen, U3 small nucleolar interacting protein 1 or histone-glutamine methyltransferase.

The FBL gene product 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. The encoded 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 (provided by RefSeq, Jul 2008).

Rabbit anti Human fibrillarin antibody detects a band of 37 kDa. The antibody has been extensively validated for western blotting using whole cell lysates.

Instructions For Use
Please refer to the PrecisionAb western blotting protocol. For additional information on secondary antibody dilution and exposure time see product web page.

Positive Control Lysate

Lysate Composition
400μg HEK293 lysate lyophilized in RIPA buffer.
Lysate Reconstitution
- If using DDT reconstitute the lyophilized lysate with 190μl DI H2O, add 200μl 2x Laemmli Sample Buffer and 10μl 2M DTT.
- If using BME reconstitute the lyophilized lysate with 180μl DI H2O, add 200μl 2x Laemmli Sample Buffer and 20μl BME.
Heat at 95°C for 5 minutes. For 10 well mini gels load 25μl. For other gel and comb formats please refer to the PrecisionAb western blotting protocol.
