  • Work with LifeSpan to design a custom immunohistochemistry to address your specific biological question. Outsource the entire localization process without having to worry about finding and characterizing target specific antibodies, sourcing and validating difficult-to-find tissues, and having the ability to interpret the resulting immunostaining in relation to complex human pathologies.

  • TCR Screening Services

  • Test your therapeutic antibodies in immunohistochemistry against a broad panel of normal frozen human tissue types in order to determine potential unintended binding. Our non-GLP TCR services are designed on the FDA recommendation outlined in their "Points to Consider in the Manufacture and Testing of Monoclonal Antibody Products for Human Use".

Specificity and Use

FBL / FIB / Fibrillarin antibody was raised against to raise this antibody, mice were injected with yeast nuclear preparations and hybridomas were screened by immunofluorescence on yeast cells and by western blotting on yeast protein homogenates.
This monoclonal antibody does not cross-react with fibrillarin in other species, but is an excellent marker of the nucleolus of yeast cells.
For western blots of yeast protein samples, use FBL / FIB / Fibrillarin antibody diluted 1:10000 (cell lysates) to 1:25000 (nuclear fractions), followed by chemiluminescent detection (ECL). For other (non-ECL) western detection methods, try the antibody diluted 1:1000-1:5000. For immunofluorescence on yeast cells, use the antibody diluted 1:2000-1:20000. We routinely dilute to 1:5000. For immunoprecipitations, use 2-4 ul for an amount of lysate derived from 5 OD600 units of yeast culture.


Tissue culture supernatant, 10 mM sodium azide.
+4°C or -20°C, Avoid repeated freezing and thawing.

FBL Antibody, FLRN Antibody, FBRL Antibody, FIB1 Antibody, Fibrillarin Antibody, RNU3IP1 Antibody, FIB Antibody

S-adenosyl-L-methionine-dependent methyltransferase that has the ability to methylate both RNAs and proteins. Involved in pre-rRNA processing by catalyzing the site-specific 2'-hydroxyl methylation of ribose moieties in pre-ribosomal RNA. Site specificity is provided by a guide RNA that base pairs with the substrate. Methylation occurs at a characteristic distance from the sequence involved in base pairing with the guide RNA.

Western blot

Western blot
Western blots of whole yeast protein extracts with a collection of our antibodies. The blot for FBL / FIB / Fibrillarin antibody is in the indicated lane, and the number indicates the SDS-PAGE molecular weight in kiloDaltons.
