GRADE & PURITYCarrier Free?Carrier-free — supplied without added carrier protein/stabilizer. Use when carriers (e.g. BSA) would interfere with conjugation or sensitive assays.Bioactive?Bioactive grade — verified to retain biological activity in functional assays. Use when the molecule must be functionally active, not just pure.Suitable for mass spectrometry (MS)?MS grade — low non-volatile and ionic residues compatible with mass spectrometry. Use to minimize background and ion suppression in MS workflows.ActiBioPure™?ActiBioPure™ — Aladdin's premier line for bioactive and recombinant products. Use when both high purity and preserved biological activity are required.Native?Native grade — protein/biomolecule in its natural (non-recombinant, non-denatured) form. Use when native structure and activity are required.EnzymoPure™?EnzymoPure™ — Aladdin's line of high-quality enzymatic solutions. Use when enzyme purity and defined activity drive assay or process performance.for Protein sequencing?Protein-sequencing grade — ultra-clean reagents for Edman/MS sequencing. Use where contaminants would obscure sequence determination.≥99.5%(HPLC)≥300U/mg protein, from mushroom
