L1CAM Protein, Human (HEK293, C-His)

The L1CAM protein is a neural cell adhesion molecule that plays a critical role in cell adhesion dynamics and initiation of tyrosine kinase receptor transmembrane signaling. Its importance spans brain development, affecting processes such as neuronal migration, axonal growth, fasciculations, and synaptogenesis. L1CAM Protein, Human (HEK293, C-His) is the recombinant human-derived L1CAM protein, expressed by HEK293 , with C-10*His labeled tag.

L1CAM, a neural cell adhesion molecule, intricately participates in the modulation of cell adhesion dynamics and the initiation of transmembrane signals at tyrosine kinase receptors. Its significance spans various stages of brain development, where it proves critical in processes such as neuronal migration, axonal growth, fasciculation, and synaptogenesis. In the mature brain, L1CAM continues to play a pivotal role in regulating the dynamics of neuronal structure and function, notably contributing to synaptic plasticity. This multifaceted protein interacts with SHTN1, with the interaction prominently occurring in axonal growth cones, and engages with isoform 2 of BSG, underscoring its involvement in diverse cellular functions.

Measured by the ability of the immobilized protein to support the adhesion of Neuro‑2A mouse neuroblastoma cells. When 5x10⁴ cells/well are added to Recombinant Human L1CAM coated plates (25 µg/mL with 100 µL/well), 42.4% will adhere for 1 hour incubation at 37 °C.

  ≥ 95%, as determined by reducing SDS-PAGE.

Lyophilized powder.

Lyophilized from a 0.22 μm filtered solution of PBS, pH 7.4.

<1 EU/μg, determined by LAL method.

It is not recommended to reconstitute to a concentration less than 100 μg/mL in ddH₂O. For long term storage it is recommended to add a carrier protein (0.1% BSA, 5% HSA, 10% FBS or 5% Trehalose).

Stored at -20°C for 2 years from date of receipt. After reconstitution, it is stable at 4°C for 1 week or -20°C for longer (with carrier protein). It is recommended to freeze aliquots at -20°C or -80°C for extended storage.

Room temperature in continental US; may vary elsewhere.
