Validation Data Gallery

• 

  Purity of recombinant human M-CSF was determined by SDS- polyacrylamide gel electrophoresis. The protein was resolved in an SDS- polyacrylamide gel in reducing and non-reducing conditions and stained using Coomassie blue.

• 

  Recombinant human M-CSF (Cat no: HZ-1192) stimulates dose-dependent proliferation of the murine mouse myloid leukemia (M-NFS-60) cell line. Cell number was quantitatively assessed by Prestoblue® Cell Viability Reagent. M-NFS-60 cells were treated with increasing concentrations of recombinant M-CSF for 48 hours. The EC50 range is 0.7-4.0 ng/mL.

  Proteintech M-CSF (Cat no: HZ-1192) demonstrates equivalent fold induction and a 2-fold better EC50 compared to leading competitors. Recombinant human M-CSF stimulates dose-dependent proliferation of the murine mouse myloid leukemia (M-NFS-60) cell line. Cell number was quantitatively assessed by Prestoblue® Cell Viability Reagent. M-NFS-60 cells were treated with increasing concentrations of recombinant M-CSF for 48 hours. The EC50 range is 0.7-4.0 ng/mL.

Background

M-CSF plays an essential role in the regulation of survival, proliferation and differentiation of hematopoietic precursor cells, especially mononuclear phagocytes. M-CSF promotes the release of proinflammatory chemokines, and thereby plays an important role in innate immunity and in inflammatory processes. It also plays an important role in the regulation of osteoclast proliferation and differentiation, the regulation of bone resorption, and is required for normal bone development. On the cellular level, M-CSF promotes reorganization of the actin cytoskeleton, regulates formation of membrane ruffles, cell adhesion and cell migration and plays a role in lipoprotein clearance (PMID: 29734839; 29679908; 28202039)

Used it to promote macrophage growth from bone marrow derived cells; used it at a conc. of 10ng/mL seems to work

• Applications: Cell culture
• Cell Tissue Type: Bone Marrow cells

we are still doing comparizon between our previous M-CSF (from another company) , for now the MCSF from proteintech works better but we still need to perfom some experiment for control (growing of BMDMs). if the results are good, we will buy your Proteintech MSCF, because it is anyway less expensive than the other one we use

• Applications: Cell culture
