IL-34 Protein, Human (CHO, His)

IL-34 protein is an important cytokine that promotes the proliferation, survival, and differentiation of monocytes and macrophages. It plays a key role in innate immune responses and inflammatory processes by promoting the release of pro-inflammatory chemokines. IL-34 Protein, Human (CHO, His) is the recombinant human-derived IL-34 protein, expressed by CHO , with C-His labeled tag.

Interleukin-34 (IL-34) is a cytokine with pivotal functions in innate immunity and inflammatory processes, as it promotes the proliferation, survival, and differentiation of monocytes and macrophages. Additionally, IL-34 plays a crucial role in the regulation of osteoclast proliferation and differentiation, influencing bone resorption. The cytokine's impact is mediated through its interaction with CSF1R, leading to the activation of downstream effectors and subsequent phosphorylation of MAPK1/ERK2 and MAPK3/ERK1. Structurally, IL-34 exists as a homodimer, and its intricate involvement in immune regulation and bone homeostasis highlights its significance in orchestrating cellular responses and maintaining tissue integrity.

Measured in a cell proliferation assay using human peripheral blood mononuclear cell and the ED₅₀ is 2-8 ng/mL.

Approximately 26.7 kDa

Greater than 95% as determined by reducing SDS-PAGE.

Lyophilized powder

Lyophilized from a 0.2 μm filtered solution of PBS, pH 7.4. Normally 5 % - 8 % trehalose, mannitol and 0.01% Tween 80 are added as protectants before lyophilization.

<1 EU/μg, determined by LAL method.

It is not recommended to reconstitute to a concentration less than 100 μg/mL in ddH₂O.

Stored at -20°C for 2 years. 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.

Room temperature in continental US; may vary elsewhere.
