No azide/low endotoxin: Aqueous buffered solution containing no preservative, 0.2µm sterile filtered. Endotoxin level is ≤0.01 EU/µg (≤0.001 ng/µg) of protein as determined by the LAL assay.

Preparation And Storage

Store undiluted at 4°C. The monoclonal antibody was purified from tissue culture supernatant or ascites by affinity chromatography. This preparation contains no preservatives, thus it should be handled under aseptic conditions.

Product Notices

  1. Since applications vary, each investigator should titrate the reagent to obtain optimal results.

Antibody Details
Down Arrow Up Arrow

The 7N4-1 antibody reacts with human IFN-α2b and to a lesser extent with IFN-α7.  It does not react with IFN-α1 nor IFN-α4.  IFN-α2b is one of the three variants of IFN-α2 that have been isolated from human cell lines. IFN-α2b is the variant predominantly produced by human leukocytes.  Human IFN-α2b belongs to the IFN-α class of proteins also known as leukocyte interferons. IFN-α comprises a family of related but distinct proteins with molecular weights ranging from 16-27 kDa with antiviral, antiproliferative and immunomodulatory activities.  The IFN-α family is composed from as many as 14 different genes.  The immunogen used to generate the 7N4-1 hybridoma was E. coli-expressed recombinant human IFN-α2b. This is a neutralizing antibody.

NA/LE refers to the culture and purification methods and buffer used to produce purified antibodies with no azide and low endotoxin: Aqueous buffered solution containing no preservative, 0.2µm sterile filtered. Endotoxin level is ≤0.01 EU/µg (≤0.001 ng/µg) of protein as determined by the LAL assay.NA/LE are perfectly suited to be used in culture or in vivo (for nonhuman studies) for functional assays — blocking, neutralizing, activation or depletion — where the presence of azide may damage cells or exogenous endotoxin may signal or activate cells.
