Anti-Sox-2, clone 1A2, ZooMab, Cat. No. ZRB5603, is a highly specific recombinant rabbit monoclonal antibody antibody that detects human and mouse Sox-2 and has been tested for use in Immunocytochemistry, Immunohistochemistry (Paraffin), and Western Blotting.
Western Blotting Analysis: A 1:1,000 dilution from a representative lot detected Sox-2 in Human H9 stem cells and in NTERA2 cells.

Immunocytochemistry Analysis: A 1:100 dilution from a representative lot detected Sox-2 in NTERA2 and H9 cells.

Immunohistochemistry (Paraffin) Analysis: A 1:200 dilution from a representative lot detected Sox-2 in E16.5 mouse embryo tissue sections.

Target description

Transcription factor SOX-2 (UniProt: P48431; also known as SOX-2, Sex determining region Y-box 2, SRY-related HMG-box gene 2) is encoded by the SOX2 gene (Gene ID: 6657) in human. SOX-2 is a transcription factor that forms a trimeric complex with OCT4 on DNA and controls the expression of a number of genes involved in embryonic development such as YES1, FGF4, UTF1 and ZFP206. It is shown to be critical for early embryogenesis and for embryonic stem cell pluripotency. It may function as a switch in neuronal development. It allows neural cells in undifferentiated state by counteracting the activity of proneural proteins and suppresses neuronal differentiation. Sumoylation of SOX-2 is shown to inhibit binding on DNA and negatively regulate the FGF4 transactivation. Defects in SOX2 gene are linked to microphthalmia that is characterized by eye malformation ranging from small eye size of a single eye to complete bilateral absence of ocular tissue. This ZooMAb recombinant monoclonal antibody, generated by our propriety technology, offers significantly enhanced specificity, affinity, reproducibility, and stability over conventional monoclonals.

Physical form

Purified recombinant rabbit monoclonal antibody IgG, lyophilized in PBS with 5% Trehalose, normal appearance a coarse or translucent resin. Contains no biocide or preservatives, such as azide, or any animal by-products. Larger pack sizes provided as multiples of 25 μL.


30 μg/mL after reconstitution at 25 μL. Please refer to guidance on suggested starting dilutions and/or titers per application and sample type.

Storage and Stability

Recommend storage of lyophilized product at 2-8°C; Before reconstitution, micro-centrifuge vials briefly to spin down material to bottom of the vial; Reconstitute each vial by adding 25 μL of filtered lab grade water or PBS; Reconstituted antibodies can be stored at 2-8°C, or -20°C for long term storage. Avoid repeated freeze-thaws.
