  • Synonym
    Laminin 111 E8
  • Source
    Human Laminin 111 E8, Fc Tag, premium grade(LA1-H5269) is expressed from human 293 cells (HEK293). It contains AA Phe 1878 - Gln 2700 (Laminin lpha1E8) & Asp 1714 – Leu 1786 (Laminin beta1E8) & Asp 1528 – Pro 1609 (Laminin gamma1E8) (Accession # P25391 (Laminin lpha1E8) & P07942 (Laminin beta1E8) & P11047 (Laminin gamma1E8)).
    Predicted N-terminus: Phe 1878 (Laminin lpha1E8) & Pro (Laminin beta1E8) & Pro (Laminin gamma1E8)
    It is produced under our rigorous quality control system that incorporates a comprehensive set of tests including sterility and endotoxin tests. Product performance is carefully validated and tested for compatibility for cell culture use or any other applications in the early preclinical stage. When ready to transition into later clinical phases, we also offer a custom GMP protein service that tailors to your needs. We will work with you to customize and develop a GMP-grade product in accordance with your requests that also meets the requirements for raw and ancillary materials use in cell manufacturing of cell-based therapies.
  • Molecular Characterization

    This protein carries a human IgG1 Fc tag at the N-terminus

    The protein has a calculated MW of 94.0 kDa & 35.0 kDa & 35.7 kDa. The protein migrates as 70-80 kDa and 116-125 kDa under non-reducing (NR) condition (SDS-PAGE) due to glycosylation.

  • Endotoxin
    Less than 0.005 EU per μg by the LAL method.
  • Sterility
    The sterility testing was performed by membrane filtration method.
  • Mycoplasma
    Negative.
  • Purity

    >90% as determined by SDS-PAGE.

  • Formulation

    Lyophilized from 0.22 μm filtered solution in 51 mM Tris,100 mM Glycine,25 mM Arginine,150 mM NaCl,pH7.5 with trehalose as protectant.
