简介
Periostin/OSF-2 Protein, a multifaceted regulator, induces cell attachment and spreading, participates in cell adhesion, and enhances BMP1 incorporation into the fibronectin matrix. It forms a structural homodimer and interacts with BMP1 and fibronectin. This interplay positions Periostin as a key player in regulating cellular and tissue functions, including cell adhesion, tissue architecture, and extracellular matrix modulation. Periostin/OSF-2 Protein, Rat (HEK293, His) is the recombinant rat-derived Periostin/OSF-2 protein, expressed by HEK293 , with C-6*His labeled tag.

稳定性测试
The thermal stability is described by the loss rate. The loss rate was determined by accelerated thermal degradation test, that is, incubate the protein at 37℃ for 48h, and no obvious degradation and precipitation were observed. The loss rate isless than 8% within the expiration date under appropriate storage condition.

Protein Description
Periostin, also known as OSF-2 (osteoblast-specific factor 2), is an extracellular matrix protein primarily involved in bone and soft tissue remodeling. It plays a critical role in various physiological processes, including cell adhesion, migration, and differentiation, as well as in the healing of injuries and the maintenance of tissue integrity. Research has shown that periostin is overexpressed in several pathological conditions, such as cancer progression, tissue fibrosis, and chronic inflammatory diseases, underscoring its importance in both normal physiological and pathological contexts. The recombinant form of periostin has gained attention for its potential therapeutic applications, particularly in regenerative medicine and tissue engineering. Studies have demonstrated that periostin can enhance the proliferation and differentiation of various cell types, including fibroblasts and osteoblasts, suggesting its utility in promoting tissue repair and regeneration. Additionally, understanding the molecular mechanisms underlying periostin's functions could advance the development of targeted therapies for diseases associated with its dysregulation. The ongoing research focuses on characterizing the effects of recombinant periostin in different biological settings and exploring its potential for clinical applications, particularly in enhancing healing processes and improving outcomes in tissue repair.
