Introduction
HEXA is the alpha subunit of the lysosomal enzyme beta-hexosaminidase which, combined with the cofactor GM2 activator protein, catalyzes the degradation of the ganglioside GM2, and other molecules having N-acetyl hexosamines terminus. The two subunits composing Beta-hexosaminidase, alpha and beta, belong to the glycosyl hydrolases family and are encoded by distinct genes. Alpha subunit gene mutations can cause Tay-Sachs disease (GM2-gangliosidosis type I).
Description
HEXA produced in Sf9 Baculovirus cells is a single,
glycosylated polypeptide chain containing 513 amino acids (23-529a.a.) and
having a molecular mass of 59.2kDa.
(Molecular size on SDS-PAGE will appear at
approximately 50-70kDa).
HEXA is expressed with a 6 amino acid His tag at
C-Terminus and purified by proprietary chromatographic techniques.
Source
Sf9,
Baculovirus cells.
Physical Appearance
Sterile Filtered colorless solution.
Formulation
HEXA protein solution (0. 5mg/ml) contains phosphate
buffered saline (pH7.4).
Stability
Store at 4°C if entire vial will be used within 2-4 weeks. Store, frozen at -20°C for longer periods of time.
For long term storage it is recommended to add a carrier protein (0.1% HSA or BSA).
Avoid multiple freeze-thaw cycles.
Purity
Greater than 90% as determined by SDS-PAGE.
