Recombinant Human Beta-defensin 4A(DEFB4A) expressed in E.coli
MW: 31.3 kDa; Buffer composition: Tris-based buffer with 50% glycerol.
Uniprot ID: O15263; Host: Homo sapiens (Human); Expression system: E.coli; Expression region: 1-64aa; Sequence information: Full Length ; Tag: N-terminal GST-tagged; Purity: Greater than 90% as determined by SDS-PAGE.
human, mouse or other beta β- and alpha α- defensins are expressed by neutrophils ( α- ), lymphocytes and epithelial cells. DEFA DEFB genes defend the host against pathogens. GENTAUR supplies anti-defensins, monclonals, polyclonals antisera and recombinant DEFs or peptides of defensin.
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.
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.
