Anti-SALL4 Antibody, clone 1H18 ZooMAb^® Rabbit Monoclonal

Sal-like protein 4 (UniProt: Q9UJQ4; also known as Zinc finger protein 797, Zinc finger protein SALL4) is encoded by the SALL4 (also known as ZNF797) gene (Gene ID: 57167) in human. Sal-like protein 4 is a Transcription factor belongs to the spalt-like protein family with a key role in the maintenance and self-renewal of embryonic and hematopoietic stem cells. SALL4 is characterized with a multiple zinc finger (ZnF) domains including one N-terminal C2HC-type ZnF and seven C2H2-type ZnF domains. SALL4 is primarily localized in the nucleus, consistent with its function as a transcription factor. In vertebrates, its found in testis, thyroid gland and is abundantly expressed in both embryonic and adult stem/stem-like cells. The expression is tightly regulated, as inappropriate expression is associated with developmental abnormalities and cancer. It is suggested to play a role in the pathogenesis of leukemia stem cells and is reported to be constitutively expressed in human acute myeloid leukemia (AML) and induces AML in transgenic mice. It has some role in All-trans retinoic acid (ATRA)-based regimes in case of leukemia therapy. Additionally, aberrant expression of SALL4 is linked to various cancers, gastric cancer, hepatocellular cancer (HCC) and colorectal cancer (CRC), where it supports the proliferation and survival of cancer cells, often correlating with a poor prognosis. It may also act as a biomarker for HCC. SALL4 plays a crucial role in the maintenance of pluripotency and self-renewal in embryonic stem cells. It interacts with other key pluripotency factors, such as OCT4 and NANOG, forming regulatory networks essential for stem cell function. Defects in this SALL4 gene are a known cause of a rare genetic disorder Okihiro/Duane-radial ray syndrome (DRRS), which involves limb and heart defects, among other symptoms. The mutation or dysfunction of the SALL4 gene leads to this developmental syndrome, underscoring its importance in normal embryonic development. This ZooMAb^® recombinant monoclonal antibody, generated by our proprietary technology, offers significantly enhanced specificity, affinity, reproducibility, and stability over conventional monoclonals.

Clone 1H18 is a ZooMAb^® recombinant rabbit monoclonal antibody that specifically detects SALL4. It targets an epitope within 25 amino acids from the C-terminal region.

Purified recombinant rabbit monoclonal antibody IgG, lyophilized in PBS with 5% Trehalose, normal appearance a coarse or translucent resin. The PBS/trehalose components in the ZooMAb formulation can have the appearance of a semi-solid (bead like gel) after lyophilization. This is a normal phenomenon. Please follow the recommended reconstitution procedure in the data sheet to dissolve the semi-solid, bead-like, gel-appearing material. The resulting antibody solution is completely stable and functional as proven by full functional testing. Contains no biocide or preservatives, such as azide, or any animal by-products. Larger pack sizes provided as multiples of 25 µL.

Reconstitute lyophilized antibody pellet with 25μL of ultrapure water or Phosphate Buffered Saline (PBS). Please refer to our reconstitution protocol and the specific application guidance on the suggested starting dilutions and sample type.

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.
