M-CSF Protein, Human (Tag free, HEK293)

Customer Review

Based on 1 Customer Validation

The M-CSF protein is an important cytokine that modulates hematopoietic precursor cells, especially mononuclear phagocytes, affecting innate immunity and inflammation through the release of proinflammatory chemokines. It is essential for osteoclast proliferation and regulates bone resorption, bone development and fertility. M-CSF Protein, Human (Tag free, HEK293) is the recombinant human-derived M-CSF protein, expressed by HEK293 , with tag free.

Biological Activity

Description

The M-CSF protein is an important cytokine that modulates hematopoietic precursor cells, especially mononuclear phagocytes, affecting innate immunity and inflammation through the release of proinflammatory chemokines. It is essential for osteoclast proliferation and regulates bone resorption, bone development and fertility. M-CSF Protein, Human (Tag free, HEK293) is the recombinant human-derived M-CSF protein, expressed by HEK293 , with tag free.

Background

M-CSF Protein is a vital cytokine involved in regulating the survival, proliferation, and differentiation of hematopoietic precursor cells, particularly mononuclear phagocytes like macrophages and monocytes. It plays a crucial role in innate immunity and inflammatory processes by promoting the release of pro-inflammatory chemokines. Additionally, M-CSF Protein is essential for osteoclast proliferation and differentiation, regulating bone resorption, and normal bone development. It is also necessary for normal male and female fertility. Moreover, M-CSF Protein contributes to the reorganization of the actin cytoskeleton, facilitating membrane ruffle formation, cell adhesion, and cell migration. Furthermore, it plays a role in lipoprotein clearance. M-CSF Protein can exist in different forms, such as homodimer or heterodimer configurations, and it interacts with CSF1R.

Verified Bioactivity

Product Properties

Appearance

Lyophilized powder

Formulation

Lyophilized from a 0.2 μm filtered solution of PBS, pH 7.4, 8% trehalose.

Endotoxin Level

< 1 EU/μg of protein by gel clotting method

Reconstitution

It is not recommended to reconstitute to a concentration less than 100 μg/mL in ddH2O. For long term storage it is recommended to add a carrier protein (0.1% BSA, 5% HSA, 10% FBS or 5% Trehalose).

Storage & Stability

Stored at -20°C for 2 years from date of receipt. After reconstitution, it is stable at 4°C for 1 week or -20°C for longer (with carrier protein). It is recommended to freeze aliquots at -20°C or -80°C for extended storage.
