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.ActiBioPure™?ActiBioPure™ — Aladdin's premier line for bioactive and recombinant products. Use when both high purity and preserved biological activity are required.≥90%(SDS-PAGE)See COA

Biochemische und physiologische Mechanismen
STAT1 is a member of the STAT protein family. In response to cytokines and growth factors, STAT family members are phosphorylated by the receptor-associated kinases, and then form homo- or heterodimers that translocate to the cell nucleus where they act a

Häufig gestellte Fragen
What is the purity of this product, and how is it determined?
This product is supplied at ≥90% purity, determined by SDS-PAGE. Lot-specific values are stated on the Certificate of Analysis.
What does Carrier Free mean?
Carrier Free indicates that the material has been processed and tested for specialty industrial processing. Specifications focus on the impurities that affect performance in that application — for example, metal content for electronics, particle size for batteries, refractive index for optics, or moisture content for moisture-sensitive processes.
What does Bioactive mean?
Bioactive indicates that the product has been processed and tested for biological and biochemical applications. Specifications may include endotoxin limits, microbial controls, sterility, low DNase/RNase/protease activity, and verified biological activity where relevant.
How should this product be stored?
Store at ?20 °C. Avoid repeated freeze–thaw cycles. Aliquot into single-use volumes before freezing.
How is this product shipped?
This product ships in an insulated container with ice pads. Unpack on arrival and transfer it to the storage condition stated above.
What documentation is provided?
Available product documentation, including Certificates of Analysis (COA), Safety Data Sheets (SDS), and specification sheets, is shown in the product document area. Document availability and access follow the current site policy.
