GM2A Protein, Human (HEK293, His)

Ganglioside GM2 activator (GM2A) is a small glycolipid transport protein which acts as a substrate specific co-factor for the lysosomal enzyme beta-hexosaminidase A. GM2A catalyzes the degradation of the ganglioside GM2 as well as affects lipid storage and neuromuscular process controlling balance. GM2A Protein, Human (HEK293, His) is the recombinant human-derived GM2A protein, expressed by HEK293 , with C-6*His labeled tag.

Ganglioside GM2 activator (GM2A) is a small glycolipid transport protein which acts as a substrate specific co-factor for the lysosomal enzyme beta-hexosaminidase A. GM2A, together with beta-hexosaminidase A, catalyzes the degradation of the ganglioside GM2, and other molecules containing terminal N-acetyl hexosamines. Mutations in GM2A result in GM2-gangliosidosis type AB or the AB variant of Tay-Sachs disease.
The large binding pocket can accommodate several single chain phospholipids and fatty acids, GM2A also exhibits calcium-independent phospholipase activity, cholesterol transfer activity as well as affects lipid storage and neuromuscular process controlling balance^[1][2].

Lyophilized powder

Lyophilized from a 0.22 μm filtered solution of 20 mM Tris-HCl, 150 mM NaCl, pH 7.5.
Note: For SPR assay, please replace the buffer. Primary amine components (e.g., Tris, imidazole) can affect protein-coupled chips.

<1 EU/μg, determined by LAL method.

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).

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.

Room temperature in continental US; may vary elsewhere.
