      DescriptionIkBa Protein, activated, 250 µg
      OverviewMillipore’s Universal Transportation Medium (UTM) is room temperature, sterile, stable medium which can sustain viability (and infectivity) of a pleurality of organisms that include clinically important viruses, chlamidyiae, mycoplasmas, or ureaplasmas during transit to the testing laboratory. UTM is provided with labeled capture-cap vials designed for transport of a sample. The capture cap is designed to secure the shaft of the swab sample to the cap, eliminating the use of forceps to remove the swab in the laboratory.

      The formulation consists of modified Hank’s balanced salt solution supplemented with bovine serum albumin, cysteine, gelatin, sucrose and glutamic acid. The pH is buffered with HEPES buffer. Phenol red is used to indicate pH. Vancomycin, amphotericin B, and colistin are incorporated in the medium to inhibit growth of competing bacteria and yeast.

      Background InformationIκBα is a cellular protein that inhibits the transcription factor NF-κB. NF-κB plays a central role in cellular stress and inflammatory responses by controlling cytokine-inducible gene expression and lymphocyte stimulation by antigens. In non-stimulated cells NF-κB is sequestered in the cytoplasm via the inhibitory protein IκBα, which obscures the nuclear localization signal of NF-κB and also blocks its ability to bind DNA. In response to various stimuli, including viral infection, ultraviolet radiation and inflammatory cytokines, IκBα is phosphorylated by the protein kinase complex IKK, which triggers its rapid degradation by ubiquitin mediated proteolysis. The liberated NF-κB then translocates to the nucleus and activates the expression of target genes. Mutations in the gene for IκBα result in the functional impairment of NF-κB which causes a decreased production of proinflammatory cytokines and certain interferons, rendering patients susceptible to infection.
