BSP2 Protein, Mouse (HEK293, His)

Customer Review

Based on 1 Customer Validation

BSP2 Protein, Mouse (HEK293, His) is a recombinant mouse bone sialoprotein 2 produced in HEK293 cells. Bone Sialoprotein 2, one of the major bone matrix proteins, with its previously known role in osseous tissue degradation, has been recently proven to play a role in the nucleation of hydroxyl apatite during osseous tissue mineralization.

Biological Activity

Description

BSP2 Protein, Mouse (HEK293, His) is a recombinant mouse bone sialoprotein 2 produced in HEK293 cells. Bone Sialoprotein 2, one of the major bone matrix proteins, with its previously known role in osseous tissue degradation, has been recently proven to play a role in the nucleation of hydroxyl apatite during osseous tissue mineralization[1].

Background

Bone Sialoprotein (BSP) is a member of the "Small Integrin-Binding Ligand N-linked Glycoproteins" (SIBLING) extracellular matrix protein family of mineralized tissues. BSP has been less studied than other SIBLING proteins such as Osteopontin (OPN), which is coexpressed with it in several skeletal cell types[2].

Verified Bioactivity

Measured by the ability of the immobilized protein to support the adhesion of MCF-7 human breast cancer cells. When 5×104 cells/well are added to mouse BSP2 coated plates (3 µg/mL with 100 µL/well), approximately 60.05% will adhere after 30 minutes at 37 °C.

Product Properties

Appearance

Lyophilized powder.

Formulation

Lyophilized after extensive dialysis against PBS, pH 7.4.

Endotoxin Level

<1 EU/μg, determined by LAL 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.

Shipping

Room temperature in continental US; may vary elsewhere.
