Product Description

The ALK Activation Antibody Sampler Kit provides an economical means to evaluate the activation status of multiple members of the ALK pathway, including phosphorylated ALK, Jak2, Jak3, Stat3, Stat5, PLCγ1, Akt, Src, and p44/42 MAPK. The kit includes enough antibody to perform two western blot experiments with each primary antibody.


Specificity / Sensitivity

Each antibody in the ALK Activation Antibody Sampler Kit recognizes the phosphorylated form of its specific target. Phospho-ALK (Tyr1586) (3B4) Rabbit mAb may cross-react with other activated protein tyrosine kinases including EGFR. Phospho-Jak2 (Tyr1007) (D15E2) Rabbit mAb may cross react with phosphorylated Jak3 and Tyk2. Phospho-Src Family (Tyr416) (D49G4) Rabbit mAb may cross react with overexpressed phosphorylated RTKs.


Source / Purification

Rabbit monoclonal antibodies are produced by immunizing animals with synthetic phosphopeptides corresponding to residues surrounding Tyr1586 of human ALK, Tyr1007 of human Jak2, Tyr980/981 of human and mouse Jak3, Tyr705 of mouse Stat3, Tyr694 of human Stat5a, Thr202/Tyr204 of human p44 MAP kinase, Ser473 of human Akt, Tyr416 of human Src, or Tyr783 of human PLCγ1 protein.

Anaplastic lymphoma kinase (ALK) is a tyrosine kinase receptor for pleiotrophin (PTN), a growth factor involved in embryonic brain development (1-3). In ALK-expressing cells, PTN induces phosphorylation of both ALK and the downstream effectors IRS-1, Shc, PLCγ, and PI3 kinase (1). ALK was originally discovered as a nucleophosmin (NPM)-ALK fusion protein produced by a translocation (4). Investigators have found that the NPM-ALK fusion protein is a constitutively active, oncogenic tyrosine kinase associated with anaplastic lymphoma (4). Research literature suggests that activation of PLCγ by NPM-ALK may be a crucial step for its mitogenic activity and involved in the pathogenesis of anaplastic lymphomas (5).

A distinct ALK oncogenic fusion protein involving ALK and echinoderm microtubule-associated protein like 4 (EML4) has been described in the research literature from a non-small cell lung cancer (NSCLC) cell line, with corresponding fusion transcripts present in some cases of lung adenocarcinoma. The short, amino-terminal region of the microtubule-associated protein EML4 is fused to the kinase domain of ALK (6-8).
