GRADE & PURITYAnimal 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.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 HEK293; See COA

Recombinant Human TXNDC4 Protein (rp188248) - SDS-PAGE
3 μg/lane of Recombinant Human TXNDC4 Protein was resolved with SDS-PAGE under reducing (R) and non-reducing (N) conditions and visualized by Coomassie® Blue staining, showing a band at 44.0 kDa under reducing conditions and 42.3 kDa under non-reducing conditions.
There are multiple pairs of disulfide bonds in the protein sequence. Disulfide bonds may cause the protein to present as a polymer in a non-reducing conditions (Uniprot ID: Q9BS26).
