Clone 1D13 is a ZooMAb^® rabbit recombinant monoclonal antibody that specifically detects the short isoform of Serine/threonine-protein kinase DCLK1. It targets an epitope within 10 amino acids from the N-terminal region.

Serine/threonine-protein kinase DCLK1 (UniProt: O15075; also known as EC: 2.7.11.1, Doublecortin domain-containing protein 3A, Doublecortin-like and CAM kinase-like 1, Doublecortin-like kinase 1) is encoded by the DCLK1 (also known as DCAMKL1, DCDC3A, KIAA0369) gene (Gene ID: 9201) in human. DCLK1, an integral component of plasma membrane, is highly expressed in fetal brain tissue and is also detectable in lung and liver. Its expression is reported to be critical for growth of human colon cancer cells and it is up-regulated in response to growth factors resulting in hyperproliferation. Both long (L) (~80-82 kDa) and short (S) (~45-50 kDa) isoforms of DCLK1 have been described. The long isoform contains two N-terminal doublecortin domains, which bind microtubules, a C-terminal serine/threonine kinase domain with homology to CaM kinases, and a middle serine/proline rich domain that mediates protein interactions. The short isoform, DCLK1-S, has been reported in human colorectal cancer cells and in cancer stem cells. The short isoform lacks the two N-terminal doublecortin domains. It is not a splice variant, but is expressed from an alternate beta promoter in intron V of the gene that results in the presence of the unique sequence of amino acids. These amino acids are absent in the long isoform, which is expressed by the alpha promoter in the 5 region of the gene. It has been reported that the 5′ (alpha)-promoter of the human DCLK1 gene becomes epigenetically silenced during colon carcinogenesis, resulting in loss of expression of the canonical long isoform in human colorectal adenocarcinomas (hCRCs). Instead, hCRCs express the short isoform. Colon tumors and normal colons from mice are reported to only express the long isoform, since the epigenetics of colon carcinogenesis in mice is significantly different from that in humans. This ZooMAbZooMAb^® recombinant monoclonal antibody, generated by our propriety technology, offers significantly enhanced specificity, affinity, reproducibility, and stability over conventional monoclonals.

KLH-conjugated linear peptide corresponding to 10 amino acids from the N-terminal region of the short isoform of human Serine/threonine-protein kinase DCLK1 (isoform 3).

Purified recombinant rabbit monoclonal antibody IgG, lyophilized in PBS, 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.

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.

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.
