  • Source
    Human M-CSF Protein, premium grade(MCF-H5218) is expressed from human 293 cells (HEK293). It contains AA Glu 33 - Arg 255 (Accession # P09603-1).
    Predicted N-terminus: Glu 33
    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
    M-CSF Structure

    This protein carries no "tag".

    The protein has a calculated MW of 25.1 kDa. The protein migrates as 39 kDa±3 kDa when calibrated against Star Ribbon Pre-stained Protein Marker under reducing (R) condition (SDS-PAGE) due to glycosylation.

  • Endotoxin
    Less than 0.01 EU per μg by the LAL method.
  • Host Cell Protein
    <0.5 ng/µg of protein tested by ELISA.
  • Host Cell DNA
    <0.02 ng/μg of protein tested by qPCR.
  • Sterility
    Negative
  • Mycoplasma
    Negative.
  • Purity

    >95% as determined by SDS-PAGE.

    >90% as determined by SEC-MALS.

  • Formulation

    Lyophilized from 0.22 μm filtered solution in PBS, pH7.4 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

    For long term storage, the product should be stored at lyophilized state at -20°C or lower.

    Please avoid repeated freeze-thaw cycles.

    This product is stable after storage at:

    1. -20°C to -70°C for 24 months in lyophilized state;
    2. -70°C for 3 months under sterile conditions after reconstitution.
SDS-PAGE
M-CSF SDS-PAGE

Human M-CSF Protein, premium grade on SDS-PAGE under reducing (R) and non-reducing (NR) conditions. The gel was stained with Coomassie Blue. The purity of the protein is greater than 95% (With Star Ribbon Pre-stained Protein Marker).

SEC-MALS
M-CSF MALS images

The purity of Human M-CSF Protein, premium grade (Cat. No. MCF-H5218) is more than 90% and the molecular weight of this protein is around 65-80 kDa verified by SEC-MALS.

Bioactivity-Bioactivity CELL BASE
 M-CSF CELL

Human M-CSF Protein, premium grade (Cat. No. MCF-H5218) stimulates proliferation of M-NFS-60 cells. The specific activity of Human M-CSF Protein, premium grade is>6.00 x 10^7 IU/mg, which is calibrated against WHO International Standard (NIBSC code: 89/512) (QC tested).

Bioactivity-ELISA
 M-CSF ELISA

Immobilized Human M-CSF Protein, premium grade (Cat. No. MCF-H5218) at 5 μg/mL (100 μL/well) can bind Human M-CSF R Protein, Fc Tag (Cat. No. CSR-H5258) with a linear range of 0.2-3.1 ng/mL (QC tested).

  • Background
    The colony stimulating factor 1 (CSF1), also known as macrophage colony-stimulating factor (M-CSF), is a secreted cytokine which influences hematopoietic stem cells to differentiate into macrophages or other related cell types. Eukaryotic cells also produce M-CSF in order to combat intercellular viral infection. It is one of the three experimentally described colony-stimulating factors. M-CSF binds to the colony stimulating factor 1 receptor. Macrophage colony-stimulating factor has been shown to interact with PIK3R2. M-CSF (or CSF-1) is a hematopoietic growth factor that is involved in the proliferation, differentiation, and survival of monocytes, macrophages, and bone marrow progenitor cells. Locally produced M-CSF in the vessel wall contributes to the development and progression of atherosclerosis.
