Scientific Data

Immunocytochemistry SOX21 antibody in NTera-2 Human Cell Line by Immunocytochemistry (ICC). View Larger

SOX21 in NTera‑2 Human Cell Line. SOX21 was detected in immersion fixed NTera-2 human testicular embryonic carcinoma cell line using Goat Anti-Human SOX21 Antigen Affinity-purified Polyclonal Antibody (Catalog # AF3538) at 10 µg/mL for 3 hours at room temperature. Cells were stained using the NorthernLights™ 557-conjugated Anti-Goat IgG Secondary Antibody (red; Catalog # NL001) and counterstained with DAPI (blue). Specific staining was localized to nuclei.

Background: SOX21

SOX21 is a member of the B group of the SOX family HMG-box transcription factors. It is a 276 amino acid residue protein that has an N-terminal HMG-box and a C‑terminal domain that is required for the SOX21 neurogenesis function. Human and mouse SOX 21 share 99% amino acid sequence identity.
