An NAD-dependent ADP-ribosyltransferase (ADPRT). Catalyzes the transfer of the ADP ribosyl moiety of oxidized NAD (NAD(+)) onto eukaryotic elongation factor 2 (eEF-2) thus arresting protein synthesis.
Recombinant Pseudomonas aeruginosa Exotoxin A (eta), partial — An NAD-dependent ADP-ribosyltransferase (ADPRT). Purity >85%. Suitable for ELISA and Western Blot applications.
SDS-PAGE: Single band at expected molecular weight confirming purity.
ELISA: Suitable as coating antigen or detection standard.
Western Blot: Compatible with standard Western Blot protocols.
Protein Interaction: Validated for SPR (Surface Plasmon Resonance) and BLI (Bio-Layer Interferometry) studies.
Shipping: Shipped at ambient temperature. Lyophilized protein is stable during transit.
Storage: Store lyophilized protein at -20°C to -80°C. Reconstituted protein should be aliquoted and stored at -80°C. Avoid repeated freeze-thaw cycles.
Shelf Life: 12 months from date of receipt when stored as recommended.
Shipping Time: Orders placed before 2 PM EST ship same day. International orders typically deliver within 5-10 business days.
