• Specifications
  Uniprot ID: Q8WX92; Host: Homo sapiens (Human); Expression system: E.coli; Expression region: 8-199aa; Sequence information: Partial; Tag: N-terminal GST-tagged; Purity: Greater than 90% as determined by SDS-PAGE.
• Additional_information
  MW: 48.9 kDa; Buffer composition: Tris-based buffer with 50% glycerol.
• Storage_and_shipping
  Shipped on ice packs (+4°C). The shelf life is related to many factors, storage state, buffer ingredients, storage temperature and the stability of the protein itself. Generally, the shelf life of liquid form is 6 months at -20°C/-80°C. The shelf life of lyophilized form is 12 months at -20°C/-80°C. Repeated freezing and thawing should be avoided. Store working aliquots at 4°C for up to one week.
• Notes
  For research use only.
• Additional description
  Aplha, transcription related growth factors and stimulating factors or repressing nuclear factors are complex subunits of proteins involved in cell differentiation. Complex subunit associated factors are involved in hybridoma growth, Eosinohils, eritroid proliferation and derived from promotor binding stimulating subunits on the DNA binding complex. NFKB 105 subunit for example is a polypetide gene enhancer of genes in B cells. Negative control peptides or isotypes available of the different species.
• Properties
  Human proteins, cDNA and human recombinants are used in human reactive ELISA kits and to produce anti-human mono and polyclonal antibodies. Modern humans (Homo sapiens, primarily ssp. Homo sapiens sapiens). Depending on the epitopes used human ELISA kits can be cross reactive to many other species. Mainly analyzed are human serum, plasma, urine, saliva, human cell culture supernatants and biological samples.

MeSH Data

• Name
  Negative Staining
• Concept
  Scope note: The technique of washing tissue specimens with a concentrated solution of a heavy metal salt and letting it dry. The specimen will be covered with a very thin layer of the metal salt, being excluded in areas where an adsorbed macromolecule is present. The macromolecules allow electrons from the beam of an electron microscope to pass much more readily than the heavy metal; thus, a reversed or negative image of the molecule is created.
