Envio: shipped on gel packs
Condições de armazenamento: store at -20 °C to -80 °C upon reconstitution for long-term storage
avoid freeze/thaw cycles, store in aliquot.
After adding 10 mM sodium azide the undiluted antibody (1 μg/μl) can be stored at 4°C for a short period of time
Validade: 12 months
Forma: lyophilised from a 1 mg/ml solution in PBS
Solubilidade: To prepare a 1 μg/μl PBS antibody solution add 200 μl (RNT-SCI-10010200) or 500 μl (RNT-SCI-10010500) sterile DNAse/RNAse-free distilled water. 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 to spin down (microcentrifuge) the reconstituted antibody before use and to use the supernatant only.
Descrição:
Anti-dsRNA monoclonal antibody J2 is the gold standard for the detection of dsRNA both in cultured cells and fixed paraffin-embedded histological samples.
Applications:
ELISA, IF, FACS, IHC, IP, Dot Blot, ChIP, affinity purification, immunoelectron microscopy.
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.
Specificity:
Anti-dsRNA monoclonal antibody J2 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 (40-50 species) as well as poly(I)-poly(C) and poly(A)-poly(U) have been recognised by Anti-dsRNA monoclonal antibody J2 although in some assays its affinity to poly(I)-poly(C) is about 10 times lower than that to other dsRNA antigens.
