- Basiliximab (anti-IL-2Ra), Antibody of Interleukin-2 receptor subunit αCAS: 179045-86-4Liquid 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. Recombinant ? Recombinant — produced via recombinant expression for defined sequence and consistency. Use for reproducible, animal-free proteins of known origin. ExactAb™ ? ExactAb™ — Aladdin's antibody line emphasizing precision and validated quality. Use for reliable, specificity-validated antibody applications. Low Endotoxin ? Low-endotoxin grade — endotoxin reduced to low controlled levels. Use in sensitive biological work where high endotoxin would interfere. Azide Free ? Azide-free — without sodium azide preservative. Use in conjugations, cell work, or assays where azide is toxic or inhibitory. Validated ? Validated grade — performance confirmed in defined applications before release. Use when you want documented assurance the reagent works as stated. ≥95%(SDS-PAGE&SEC-HPLC) See COA● En stock — EE. UU. Articulo #: Ab175463Vista del artículoPrecios y tamaños del paquete

Preguntas frecuentes
How do I choose the right Life Sciences for my synthesis route?
Work backwards from the target structure: identify the bonds you need to form, then pick the Life Sciences entry whose functional groups, protecting-group pattern, and stereochemistry match. Compare purity, available pack sizes, and stability under your reaction conditions before committing to a route.
What does Life Sciences cover?
Life Sciences is a top-level listing in our catalogue. Use the filters and search on the listing page to narrow by the attributes that matter for your work, or browse the neighbouring categories from the main navigation.
What specifications matter most for Life Sciences?
For Life Sciences, purity is the headline figure — 95% or better is a common floor for medicinal chemistry, and higher for late-stage steps. Also check isomeric and stereochemical purity, water content for moisture-sensitive groups, storage temperature, and that the pack size matches your scale. All products are supplied for professional research and development use only, and are not for use in humans, animals, diagnostics, or therapy.
What if the Life Sciences I need is not listed?
Search Life Sciences by CAS number or SMILES first — close analogs are often listed under a neighbouring subcategory. If nothing matches, custom synthesis and bulk enquiries go to [email protected]. We supply verified businesses, research institutions, universities, and government agencies.
