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.His Tag?His tag grade — recombinant protein bearing a His tag for affinity purification/detection. Use to purify, immobilize, or detect the tagged protein.≥85%(SDS-PAGE)expressed in E. coli; See COA

Recombinant Human HuR/ELAVL1 Protein (rp220390) - ELISA
Immobilized Recombinant Human HuR/ELAVL1 Protein (rp220390) at 1.0 μg/mL can bind Recombinant HuR/ELAVL1 Antibody (Ab109133) with the EC₅₀ of 8.13 ng/mL.
Recombinant Human HuR/ELAVL1 Protein (rp220390) - SDS-PAGE
3 μg/lane of Recombinant Human HuR/ELAVL1 Protein was resolved with SDS-PAGE under reducing (R) and non-reducing (N) conditions and visualized by Coomassie® Blue staining, showing the bands at 33.0 kDa under reducing conditions and 33.3 & 66.6 kDa under non-reducing conditions.
HuR/ELAVL1 can form homodimers (Uniprot: Q15717; PubMed:17632515, 20219472). The two bands of HuR/ELAVL1 monomer correspond to its two conformations under non-reducing conditions (PMID: 21723170).
