{"product_id":"biolegend-663703","title":"Biolegend, 663703, Anti-, 100microl","description":"\u003cp\u003eSigma transcription factor controlling the regulation of genes is required for protection against external stresses. Possibly, it affects the expression of katE (catalase HPII), xthA (endonuclease III), the appABC operon, and other genes by modifying the affinity of RNA polymerase for the promoters.\u003cbr\u003e\n100microl\u003cbr\u003e\nVerified Reactivity: E. coli\u003cbr\u003e\nAntibody Type: Monoclonal\u003cbr\u003e\nHost Species: Mouse\u003cbr\u003e\nImmunogen: Recombinant protein\u003cbr\u003e\nPreparation: Dried ascites\u003cbr\u003e\nStorage \u0026amp; Handling: Store lyophilized antibody at -20°C.\u003cbr\u003e\nApplication: WB - Quality tested ELISA - Verified FA - Reported in the literature, not verified in house\u003cbr\u003e\nRecommended Usage: Each lot of this antibody is quality control tested by Western blotting. To reconstitute, add 100 µl of ddH2O to the tube containing antibody and mix to dissolve. For Western blotting, the suggested dilution is 1:1000 after reconstitution. It is recommended that the reagent be titrated for optimal performance for each application.\u003cbr\u003e\nApplication Notes: Previously item# W0009 from Neoclone. Clone 1RS1 does not react with Shigella, Vibrio, Pseudomonas, Rhodobacter, Agrobacterium, Streptococcus, Arthobacter, or Borrelia. It recognizes epitope 33-256. Additional reported applications (for the relevant formats) include: functional assay.\u003cbr\u003e\nAdditional Product Notes: Non-specific band may be observed at 60 kD.\u003cbr\u003e\nApplication References(PubMed link indicates BioLegend citation): Nguyen LH, et al. 1993.
