    Source E.coli
    Description Recombinant Human β-Defensin 4A is produced with our E. coli expression system. The target protein is expressed with sequence (Gly24-Pro64) of Human β-Defensin 4A.
    Names Beta-Defensin 4A; Beta-Defensin 2; BD-2; hBD-2; Defensin, Beta 2; Skin-Antimicrobial Peptide 1; SAP1; DEFB4A; DEFB102; DEFB2; DEFB4; DEFB4B
    Accession # O15263
    Formulation Lyophilized from a 0.2 μm filtered solution of 20mM PB, 130mM NaCl, pH 7.4
    Shipping The product is shipped at ambient temperature.
    Reconstitution Always centrifuge tubes before opening. Do not mix by vortex or pipetting.
    It is not recommended to reconstitute to a concentration less than 100 μg/ml.
    Dissolve the lyophilized protein in 1X PBS.
    Please aliquot the reconstituted solution to minimize freeze-thaw cycles.
    Storage Lyophilized protein should be stored at < -20°C, though stable at room temperature for 3 weeks.
    Reconstituted protein solution can be stored at 4-7°C for 2-7 days.
    Aliquots of reconstituted samples are stable at < -20°C for 3 months.
    Purity Greater than 95% as determined by SEC-HPLC and reducing SDS-PAGE.
    Endotoxin Less than 0.1 ng/μg (1 IEU/μg).

    Background β-Defensin 4A is a membrane-active cationic peptide that functions in inflammation and innate immune responses. There are at least 30 β-Defensins, which are distinguished from α-Defensins by the connectivity pattern of their three intermolecular disulfide bonds. Members of the Defensin family are highly similar in protein sequence. This gene encodes Defensin, DEFB4;, which has broad-spectrum antimicrobial activity and may play an important role in innate epithelial defense. They are highly expressed in skin and tonsils, and to a lesser extent in trachea, uterus, kidney, thymus, adenoid, pharynx and tongue. β-Defensin 4A has low expression in salivary gland, bone marrow, colon, stomach, polyp and larynx. No expression in small intestine. The 45 amino acid mature human BD3 shares 38% and 33% amino acid sequence identity with mouse and rat BD3, respectively.
