Overview
Host Type: Mouse
Antibody Isotype: IgM kappa
Antibody Clonality: Monoclonal
Antibody Clone: K2
Regulatory Status: RUO
Target Species: Species Independent
Applications:
- Enzyme-Linked Immunosorbent Assay (ELISA)
- Immunofluorescence (IF)
Shipping:
The IgM mononclonal antibody K2 is only sold as hybridoma supernatant which is stored frozen and shipped on ice.
Storage:
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 mAb should be kept frozen. Repeated freezing/thawing cycles should be avoided.
Further Information
Applications Description:
MAb K2 is primarily used for a sandwich ELISA to detect and quantitate (after calibration) dsRNA (see Sch?nborn et al.). For this application it should be diluted 1:2 with PBS. It may also be advantageous to use K2 for immunofluorescence studies.
Not for use for clinical purposes. For in vitro use only.

Background:
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 is mainly used for specialised applications, where J2 and K1 - antibodies that can be shipped at ambient temperature - do not suffice. Due to its IgM isotype K2 is more prone to aggregation at high concentration, and therefore cannot be lyophilised and needs to be shipped on ice.
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.

Formulation:
Culture supernatant (RPMI, 5% fetal calf serum).
Product:
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 Sch?nborn et al. K2 binds with high avidity to all dsRNAs investigated.
Source:
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.
Synonyms:
Mouse anti dsRNA
