SCICONS mouse dsRNA antibody [K2]Catalog number: 10030005
This product is part of the SCICONS™ product line which offers the gold standard in anti-dsRNA antibodies.
Over the past decade our double-stranded RNA (dsRNA)antibodies have been used extensively to detect and characterise plant and animal viruses with dsRNA genomes or intermediates. In addition, the anti-dsRNA antibodies can be used as a diagnostic tool to detect pathogens, including detection in paraffin-embedded fixed tissue samples (Richardson et al. 2010). K2 anti-dsRNA monoclonal antibody has an IgM isotype. K2 has primarily been used in ELISA and sandwich ELISA. Generally, K2 can be used in applications where an anti-dsRNA antibody with an isotype other than IgG (IgG2a) is required.
Synonyms: Mouse anti dsRNA
Female DBA/2 mice were injected intraperitonially with a mixture of 50 ug L-dsRNA and 75 ug methylated bovine serum albumin, emulsified in complete Freund's adjuvant. After several boosts spleen cells were fused with Sp2/0-Agl4 myeloma cells to generate the hybridoma clone.
The mAb K2 recognises double-stranded RNA (dsRNA) provided that the length of the helix is greater than or equal to 40 bp dsRNA. Recognition is independent of the sequence and nucleotide composition of the antigen. All naturally occurring dsRNAs investigated up to now (4050 species) as well as poly(I).poly(C) and poly(A).poly(U) have been recognised by K2. As described by Schönborn et al. K2 binds with high avidity to all dsRNAs investigated.
Formulation: Culture supernatant (RPMI, 5% fetal calf serum). No preservative is added.
Concentration: Undiluted hybridoma supernatant
MAb K2 is primarily used for a sandwich ELISA to detect and quantitate (after calibration) dsRNA (see Schönborn et al.). For this application it should be diluted with PBS. It may also be advantageous to use K2 for immunofluorescence studies. The optimum working dilution of the antibody for any specific application should be established by titration. Not for use for clinical purposes. For in vitro use only.
After delivery antibodies should be aliquoted and stored at -20 ° or -70 °C. After adding 10 mM sodium azide undiluted antibody can also be stored at +4 °C for a short period of time. For long term storage the antibody should be kept frozen. Repeated freezing/thawing cycles should be avoided.
Shipping Conditions: The IgM mononclonal antibody K2 is only sold as hybridoma supernatant and shipped at ambient temperature.
