CAS: 9001-92-7 Cat. No.: rp227286 EC Number: 232-642-4
AVAILABLE TO ORDER
GRADE & PURITY Animal Free ? Animal-free — produced without animal-derived components to reduce contamination risk. Use in biomanufacturing and culture avoiding animal-origin material. Carrier 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. Recombinant ? Recombinant — produced via recombinant expression for defined sequence and consistency. Use for reproducible, animal-free proteins of known origin. 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. 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. ≥97%(HPLC) ≥1800U/mg protein
