Human Neutrophil defensin 1 / DEFA1 protein, Twin-Strep Tag

  • Synonym
  • Source
    Human Neutrophil defensin 1, Twin-Strep Tag (ND1-H5282) is expressed from human 293 cells (HEK293). It contains AA Asp 39 - Cys 94 (Accession # P59665-1).
  • Molecular Characterization
    Online(Asp 39 - Cys 94) P59665-1

    This protein carries a twin strep tag at the C-terminus.

    The protein has a calculated MW of 9.8 kDa. The protein migrates as 11-14 kDa under reducing (R) condition (SDS-PAGE) due to glycosylation.

  • Endotoxin
    Less than 0.01 EU per μg by the LAL method.
  • Purity

    >90% as determined by SDS-PAGE.

  • Formulation

    Lyophilized from 0.22 μm filtered solution in PBS, pH7.4. Normally trehalose is added as protectant before lyophilization.

    Contact us for customized product form or formulation.

SDS-PAGE
Human Neutrophil defensin 1, Twin-Strep Tag (Cat. No. ND1-H5282) SDS-PAGE gel

Human Neutrophil defensin 1, Twin-Strep Tag on SDS-PAGE under reducing (R) condition. The gel was stained overnight with Coomassie Blue. The purity of the protein is greater than 90%.

  • Background
    Human defensins are a family of small antimicrobial proteins found predominantly in leukocytes and epithelial cells that play important roles in the innate and adaptive immune defense against microbial infection. The α-defensins, human neutrophil peptides (HNPs) 1–3, are constitutively expressed in neutrophils and are the most abundant neutrophil granule proteins.
