Recombinant Human COMP protein, FLAG-tagged

• Cat.No.: COMP-3659H
• Product Overview: Recombinant Human COMP fused with FLAG tag at N-terminal was expressed in HEK293.

Specification

• Description: The protein encoded by this gene is a noncollagenous extracellular matrix (ECM) protein. It consists of five identical glycoprotein subunits, each with EGF-like and calcium-binding (thrombospondin-like) domains. Oligomerization results from formation of a five-stranded coiled coil and disulfides. Binding to other ECM proteins such as collagen appears to depend on divalent cations. Mutations can cause the osteochondrodysplasias pseudochondroplasia (PSACH) and multiple epiphyseal dysplasia (MED).

• Endotoxin: < 0.1 EU/ug
• Purity: Purity as determined by densitometric image analysis: >90%
• Applications: Cell culture and/or animal studies, ELISA, Western blotting
• Storage: Store lyophilized protein at –80 centigrade. Lyophilized protein remains stable until the expiry date when stored at –80 centigrade. Aliquot reconstituted protein to avoid repeated freezing/thawing cycles and store at –80 centigrade for long term storage. Reconstituted protein can be stored at 4 centigrade for a limited period of time; it does not show any change after one week at 4 centigrade.
• Reconstitution: Add deionized water to prepare a working stock solution of approximately 0.5 mg/mL and let the lyophilized pellet dissolve completely. Filter sterilize your culture media/working solutions containing this non-sterile product before using in cell culture.
