Description

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, N-His, C-Myc) is the recombinant human-derived L1CAM protein, expressed by HEK293 , with C-Myc, N-10*His labeled tag. The total length of L1CAM Protein, Human (HEK293, N-His, C-Myc) is 1101 a.a., with molecular weight of 150-200 kDa.

Background

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.

Biological Activity

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.

Molecular Weight

Approximately 150-200 kDa due to the glycosylation

Purity

Greater than 95% as determined by reducing SDS-PAGE.

Appearance

Lyophilized powder.

Formulation

Lyophilized from a 0.2 μm filtered solution of PBS, pH 7.4.

Endotoxin Level

<1 EU/μg, determined by LAL method.

Reconstitution

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).

Storage & Stability

Stored at -20°C for 2 years. 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.

Shipping

Room temperature in continental US; may vary elsewhere.

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.

The reconstitution calculator equation

Volume (to add to vial) = Mass (in vial) ÷ Desired Reconstitution Concentration

Volume (to add to vial) = Mass (in vial) ÷ Desired Reconstitution Concentration
= ÷

The dilution calculator equation

Concentration (start) × Volume (start) = Concentration (final) × Volume (final)

This equation is commonly abbreviated as: C1V1 = C2V2

Concentration (start) × Volume (start) = Concentration (final) × Volume (final)
× = ×

The specific activity calculator equation

Specific Activity (Unit/mg) = 106 ÷ Biological Activity (ED50)

Specific Activity (Unit/mg) = 106 ÷ Biological Activity (ED50)
Unit/mg = 106 ÷ ng/mL
