Biological Activity Comment
Immobilized Human L1CAM, His Tag at 0.2μg/ml (100μl/well) on the plate. Dose response curve for Anti-L1CAM Antibody, hFc Tag with the EC50 of 12.3ng/ml determined by ELISA. See testing image for detail.
Centrifuge the tube before opening. Reconstituting to a concentration more than 100 μg/mL is recommended. Dissolve the lyophilized protein in distilled water.
缓冲液
Lyophilized from 0.22μm filtered solution in PBS ( pH 7.4). Normally 8 % trehalose is added as protectant before lyophilization.
储存条件
-20 °C,-80 °C
储存方法
-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.
L1 cell adhesion molecule (L1CAM) is one of the first neural adhesion molecules described with important functions in the development of the nervous system. Subsequent work discovered that L1CAM is expressed in many human cancers and is often associated with bad prognosis. This is most likely due to the motility and invasion promoting function of L1CAM. L1CAM is a valuable diagnostic/prognostic marker and an attractive target for the therapy of several human cancers.
分子量
124.6 kDa. Due to glycosylation, the protein migrates to 150-180 kDa based on Tris-Bis PAGE result.
