Datasheets
  • Sm B/B'/N Antibody (A-5) is a mouse monoclonal IgG2a κ, cited in 2 publications, provided at 200 µg/ml
  • raised against amino acids 1-240 representing full length SmB of human origin
  • Anti-Sm B/B'/N Antibody (A-5) is recommended for detection of Sm B, Sm B′ and Sm N of mouse, rat and human origin by WB, IP, IF, IHC(P) and ELISA; also reactive with additional species, including and equine and canine
  • Anti-Sm B/B'/N Antibody (A-5) is available conjugated to agarose for IP; HRP for WB, IHC(P) and ELISA; and to either phycoerythrin or FITC for IF, IHC(P) and FCM
  • also available conjugated to Alexa Fluor® 488, Alexa Fluor® 546, Alexa Fluor® 594 or Alexa Fluor® 647 for WB (RGB), IF, IHC(P) and FCM, and for use with RGB fluorescent imaging systems, such as iBright™ FL1000, FluorChem™, Typhoon, Azure and other comparable systems
  • also available conjugated to Alexa Fluor® 680 or Alexa Fluor® 790 for WB (NIR), IF and FCM; for use with Near-Infrared (NIR) detection systems, such as LI-COR®Odyssey®, iBright™ FL1000, FluorChem™, Typhoon, Azure and other comparable systems
  • m-IgG Fc BP-HRP and m-IgG2a BP-HRP are the preferred secondary detection reagents for Sm B/B'/N Antibody (A-5) for WB and IHC(P) applications. These reagents are now offered in bundles with Sm B/B'/N Antibody (A-5) (see ordering information below).

SEE ALSO...

Sm B/B′/N Antibody (A-5) is a mouse monoclonal IgG2a kappa light chain antibody that detects Sm B/B′/N in mouse, rat, and human samples through applications such as western blotting (WB), immunoprecipitation (IP), immunofluorescence (IF), immunohistochemistry, and enzyme-linked immunosorbent assay (ELISA). Anti-Sm B/B′/N antibody (A-5) is available in both non-conjugated and various conjugated forms, including agarose, horseradish peroxidase (HRP), phycoerythrin (PE), fluorescein isothiocyanate (FITC), and multiple Alexa Fluor® conjugates. Sm B/B′/N plays a crucial role in the spliceosome, a complex responsible for processing mRNA precursors by excising introns to create continuous coding sequences. Sm B/B′/N functions as part of the small nuclear ribonucleoprotein particles (snRNPs), which are essential for the splicing process. Sm proteins, including Sm B, B′, D1, D2, D3, E, F, and G, share a conserved Sm sequence motif, which is vital for RNA processing. Antibodies against Sm proteins are often associated with autoimmune diseases, particularly systemic lupus erythematosus, highlighting Sm B/B′/N significance in both normal cellular function and disease pathology.

Can Sm B/B'/N (A-5): sc-374009 monoclonal antibody be used to stain formalin-fixed, paraffin-embedded (FFPE) tissue sections?

Asked by: jenniferc
Thank you for your question. Yes, Sm B/B'/N (A-5): sc-374009 has been validated for use in IHC with paraffin-embedded sections. We recommend performing antigen retrieval with sodium citrate buffer (pH 6) and heat. The full protocol can be found here: https://www.scbt.com/scbt/resources/protocols/immunoperoxidase-staining
