Molecular Weight	18.04 KDa
Apparent Molecular Weight	16 KDa, reducing conditions
Form	Lyophilized from a 0.2 μm filtered solution of 20mM Tris-HCl, 150mM NaCl, 2mM EDTA, pH 8.5.
Purity	Greater than 95% as determined by reducing SDS-PAGE.

Endotoxin Level	Less than 0.1 ng/µg (1 EU/µg) as determined by LAL test.

Reconstitution	Always centrifuge tubes before opening.Do not mix by vortex or pipetting. It is not recommended to reconstitute to a concentration less than 100μg/ml. Dissolve the lyophilized protein in distilled water. Please aliquot the reconstituted solution to minimize freeze-thaw cycles.
Storage	Lyophilized protein should be stored at < -20°C, though stable at room temperature for 3 weeks. Reconstituted protein solution can be stored at 4-7°C for 2-7 days. Aliquots of reconstituted samples are stable at < -20°C for 3 months.
Shipping Condition	The product is shipped at ambient temperature. Upon receipt, store it immediately at the temperature listed below.

Background	Anterior Gradient Protein 2(AG-2) and Anterior Gradient Protein 3 (AG-3) are human homologues of genes involved in differentiation, are associated with oestrogen receptor-positive breast tumours and interact with metastasis gene C4.4a and dystroglycan (hAG-3 protein). AG-3 could serve as a prognostic marker for survival in patients with low grade and high grade serous ovarian carcinomas.
