Molecular Weight	50.9 KDa
Apparent Molecular Weight	55-60 KDa, reducing conditions
Form	Lyophilized from a 0.2 μm filtered solution of 20mM PB, 500mM NaCl, pH 7.4.
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	GP100 Plays a central role in the biogenesis of melanosomes. Involved in the maturation of melanosomes from stage I to II. The transition from stage I melanosomes to stage II melanosomes involves an elongation of the vesicle, and the appearance within of distinct fibrillar structures.
