Protein Concentration25µg size is bottled at 0.2mg/mL concentration. 100 µg size is supplied at a lot-specific concentration.
Storage and HandlingBriefly centrifuge the vial upon receipt. An unopened vial can be stored at 4°C for up to 2 weeks, or at -20°C or below for up to six months. The protein may be further diluted to 0.1 mg/mL using 0.22 µm-filtered PBS, pH 7.4. For long-term storage, the diluted stock solution should be aliquoted and stored at ≤ –70°C to minimize freeze-thaw cycles. If additional dilution is required, carrier proteins such as FBS or BSA should be added to maintain protein stability.
Research AreasMetabolism

Background Information


Beta-hexosaminidases are lysosomal enzymes that hydrolyze terminal N-acetyl-D-hexosamine residues from GM2 gangliosides and globo-sphingolipids. They exist in three isoforms: Hex A (αβ), Hex B (ββ), and Hex S (αα), formed by different combinations of α and β subunits encoded by the HEXA and HEXB genes. Recombinant HEXA corresponds to Hex S and cleaves non-reducing end N-acetylgalactosamine residues from dermatan sulfate, chondroitin sulfate, and sulfated glycolipids, and is also active against 4-methylumbelliferyl-N-acetyl-β-D-glucosaminide. Mutations in HEXA cause Tay-Sachs disease, a fatal lysosomal storage disorder marked by GM2 ganglioside accumulation in neurons, typically leading to death by age 4.

Frequently Asked Questions


Why are Recombinant Proteins expressed with epitope tags?
The majority of InnoCyto's recombinantly expressed proteins are engineered with a short, well-characterized peptide sequence (e.g., His-tag, Fc-tag, Flag-tag, or similar) fused to the protein of interest. The tag enables reliable detection, purification, or immobilization of the protein using commercially available anti-tag antibodies or affinity resins, without needing a custom antibody against the native protein.

What types of tagged proteins are best for my application?
Common tag options include His-tag (for affinity purification via Ni-NTA/IMAC and detection via anti-His antibodies), Fc-tag (for use in binding assays, ELISA capture, and dimerization studies), and Flag-tag (for high-specificity detection and immunoprecipitation). Tag choice should be based on your intended workflow — purification-focused work often favors His-tag, while functional binding or capture-based assays often benefit from Fc-tag.

Does the tag affect the protein's biological activity or binding function?
Tag placement (N-terminal vs. C-terminal) and type are selected during design to minimize interference with the protein's native folding and functional binding site, and each tagged protein is validated for activity in relevant binding or functional assays. Product pages indicate the tag location and confirm the functional validation performed for that specific protein.
