Introduction
Periostin is a disulfide linked 90 kDa, 811 amino acid protein originally isolated as a osteoblast-specific factor that functions as a cell adhesion molecule for preosteoblasts and is thought to be involved in osteoblast recruitment, attachment and spreading. Additionally, periostin expression has previously been shown to be significantly increased by both transforming growth factor beta-1(TGFbeta1) and bone morphogenetic protein (BMP-2). OSF-2 has a typical signal sequence, followed by a cysteine-rich domain, a fourfold repeated domain and a C-terminal domain. The fourfold repeated domain of OSF-2 shows homology with the insect protein fasciclin. Periostin mRNA is expressed in the developing mouse embryonic and fetal heart, and that it is localized to the endocardial cushions that ultimately divide the primitive heart tube into a four-chambered heart.
BP000235-CYT-452: Recombinant Human Periostin
Source: E. coli-derived.
Containing 648 amino acid residues of the human OSF-2 and 23 additional amino acid residues - HisTag, Xa-cleavage site.
Purity > 90%, by SDS-PAGE.
Formulation: Filtered and lyophilized from 0.5 ug/ml in 0.05 M Acetate buffer pH-4.
Reconstitution: It is recommended to add 0.1 M Acetate buffer pH4 to prepare a working stock solution of approximately 0.5 ug/ml and let the lyophilized pellet dissolve completely. In higher concentrations the solubility of this antigen is limited. Product is not sterile! Please filter the product by an appropriate sterile filter before using it in the cell culture.
Applications: Elisa, WB.
Shipping: The product is shipped at ambient temperature. Upon receipt, store it immediately at the temperature recommended below.
Stability & Storage: Use a manual defrost freezer and avoid repeated freeze-thaw cycles.
12 months from date of receipt, -20 to -70°C as supplied.
1 month, 2 to 8°C under sterile conditions after reconstitution.
3 months, -20 to -70°C under sterile conditions after reconstitution.
