  • Source
    Monoclonal Anti-His Tag Antibody, Human IgG1-Acridinium ester (55F8) is a chimeric monoclonal antibody recombinantly expressed from human 293 cells (HEK293), which combines the variable region of a mouse monoclonal antibody with human IgG1 constant domain. The mouse monoclonal antibody is produced from a hybridoma resulting from fusion of SP2/0 myeloma and B-lymphocytes obtained from a mouse immunized with His.
  • Isotype
    Human IgG1/kappa
  • Specificity
    This product is a specific antibody specifically reacts with His.
  • Labeling
    Acridinium ester, can react with the primary amino group of protein. Under alkaline conditions, NHS is replaced as the leaving group, and the protein forms a stable amide bond with Acridinium ester.
  • Protein Ratio
    Passed as determined by binding MPCLIA.
  • Application
    MPCLIA
  • Purity

    >95% as determined by SDS-PAGE.

  • Endotoxin
    Less than 1.0 EU per μg by the LAL method.
  • Formulation

    Lyophilized from 0.22 μm filtered solution in PBS, pH6.3 with trehalose as protectant.

    Contact us for customized product form or formulation.

  • Reconstitution

    Please see Certificate of Analysis for specific instructions.

    For best performance, we strongly recommend you to follow the reconstitution protocol provided in the CoA.

  • Storage

Bioactivity-MPCLIA
 His MPCLIA

Immobilized 0.025 μg /Test of SARS-CoV-2 S protein RBD, His Tag (Cat. No. SPD-C52H3) to the Monoclonal Anti-His Tag Antibody, Human IgG1-Acridinium ester (55F8) (Cat. No. HIS-FM535, 0.04 μg /Test), incubated with 100 μL /Test of Anti-SARS-CoV-2 Spike RBD Neutralizing Antibody, Mouse IgG1 (AM122) (Cat. No. SCT-M369) at increasing concentration coupled to Anti-Mouse IgG-coupled Magnetic Beads (used for MPCLIA) (Cat. No. MPC-A003) (10 μg beads/Test). Detection was performed with sensitivity of 0.98 ng/mL in Magnetism particulate chemiluminescence immunoassay (MPCLIA) (KEYSMILE, SMART 6500S) (QC tested).

 His MPCLIA

The MPCLIA assay shows that Monoclonal Anti-His Tag Antibody, Human IgG1-Acridinium ester (55F8) (Cat. No. HIS-FM535) is stable after freezing and thawing 3 times.

  • Background
    His tag is a very small molecular weight tag, usually composed of 6-10 histidine (His). It is one of the commonly used tags for protein purification and detection. Due to its small molecular weight, fusion into the target protein has almost no effect on the structure and characteristics of the protein. Anti-his tag antibody can accurately detect, locate and purify His tag fusion protein, so as to provide convenience for the vast number of researchers.
