Name : Biotinylated Human ALCAM/CD166 Protein
Product Source :
Recombinant Biotinylated Human ALCAM/CD166 Protein is expressed from HEK293 with His tag and Avi tag at the C-Terminus. It contains Trp28-Ala526.[Accession | Q13740-1]
Molecular Weight :
The protein has a predicted MW of 58.9 kDa. Due to glycosylation, the protein migrates to 72-80 kDa based on Tris-Bis PAGE result.
Endotoxin Level :
Less than 1EU per ug by the LAL method.
Purity :
> 95% as determined by Tris-Bis PAGE> 95% as determined by HPLC
Formulation :
Lyophilized from 0.22μm filtered solution in PBS (pH 7.4). Normally 8% trehalose is added as protectant before lyophilization.
Reconstitution :
Centrifuge the tube before opening. Reconstituting to a concentration more than 100 μg/ml is recommended. Dissolve the lyophilized protein in distilled water.
Storage and Stability :
-20 to -80°C for 12 months as supplied from date of receipt. -80°C for 3-6 months after reconstitution. 2-8°C for 2-7 days after reconstitution. Recommend to aliquot the protein into smaller quantities for optimal storage. Please minimize freeze-thaw cycles.
Product Concentration :
Tris-Bis PAGE Biotinylated Human ALCAM on Tris-Bis PAGE under reduced condition. The purity is greater than 95%. SEC-HPLC The purity of Biotinylated Human ALCAM is greater than 95% as determined by SEC-HPLC. ELISA Data Immobilized Biotinylated Human ALCAM, His Tag at 1μg/ml (100μl/well) on the streptavidin precoated plate (5μg/ml). Dose response curve for Anti-ALCAM Antibody, hFc Tag with the EC50 of 0.18μg/ml determined by ELISA.
Background :
Brain metastasis (BM) in non-small-cell lung cancer (NSCLC) has a very poor prognosis. Recent studies have demonstrated the importance of cell adhesion molecules in tumor metastasis.Elevated levels of ALCAM expression promote BM formation in NSCLC through increased tumor cell dissemination and interaction with the brain endothelial cells. Therefore, ALCAM could be targeted to reduce the occurrence of BM.
Synonyms :
CD166; ALCAM; MEMD; CD6L; KG-CAM
