• Purity/Purification: Affinity chromatography on Protein A-agarose. Gel electrophoretically pure IgG antibody.
• Form/Format: The lyophilized sample should be reconstituted with 500ul sterile distilled water.
• Concentration: Concentration after reconstitution: 1.00mg/ml as determined by A280nm (A280nm = 1.47 corresponds to 1mg/ml antibody). (varies by lot)

• Applicable Applications for anti-double-stranded RNA (K1) antibody: ELISA (EIA), Immunoblot (IB), Immunoaffinity chromatography (IAC), Immunocytochemistry (ICC), Immunohistochemistry (IHC), Flow Cytometry
• Application Notes: MAb K1 can be used for ELISA, dsRNA-immunoblotting, immuno-affinity-chromatography and in certain systems also for immunohistochemistry (see references).; Please note that nucleic acid separation prior to dsRNA-immunoblotting must be carried out by polyacrylamide gel electrophoresis, because the sensitivity of detection is considerably lower after blotting from agarose gels.
• Source: Female DBA/2 mice were injected intraperitonially with a mixture of 50ug L-dsRNA and 75ug 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.
• Reconstitution: The mAb will then be in PBS without any stabilisers or preservatives at a concentration of 1mgr/ml. As a result of the lyophilisation procedure, the reconstituted antibody may contain small amounts of denatured protein in the form of aggregates that may interfere with some applications such as immunohistochemistry (e.g. by giving high backgrounds). We therefore highly recommend centrifuging (microcentrifuge) the reconstituted antibody before use and using the supernatant.
• Preparation and Storage: After reconstitution antibodies should be aliquoted and stored at -20 degree C or -70 degree C. After adding 10mM sodium azide undiluted antibody can also be stored at +4 degree C for a short period of time. For long term storage the mAb should be kept frozen. Repeated freezing/thawing cycles should be avoided.

The mAb K1 recognizes double-stranded RNA (dsRNA) provided that the length of the helix is greater than or equal to 40 bp. dsRNArecognition is independent of the sequence and nucleotide composition of the antigen. All naturally occurring dsRNAs investigated up to now (40-50 species) as well as poly(I).poly(C) and poly(A).poly(U) have been recognised by K1. As described by Schonborn et al. K1 shows higher affinity to poly(I).poly(C) than to the other dsRNA antigens, although the difference of apparent binding constants may vary under different experimental conditions.
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 test tool to detect pathogens, including detection in paraffin-embedded fixed tissue samples (Richardson et al. 2010).
The K1 monoclonal antibody recognizes dsRNA with similar affinity to our widely used J2 antibody. It can be used for the histological and cytological detection of dsRNA in cells and tissues.It has proven especially useful as an alternative to J2 to resolve cross-reactions and/or remove unwanted background, in those rare experimental setups where J2 did not provide satisfactory results.
K1 can be used to detect dsRNA intermediates of viruses as diverse as Hepatitis virus, Theiler's murine encephalomyelitis virus or Japanese encephalitis virus. It has been for the detection of dsRNA in cultured cells and in fixed paraffin-embedded histological samples (see publications).
If Poly I:C needs to be detected we highly using K1 rather than J2 because K1 has a much higher affinity for this synthetic polyribonucleotide (see Schonborn et al. 1991, Fig. 2).K1 has been used successfully in immunofluorescence microscopy, in flow cytometry (FACS) and in immunocapture methods (such as dot-blot and ELISA).
