Background

Contactin-4 (CNTN4) is a protein critically involved in mediating cell surface interactions essential for nervous system development. This multifunctional molecule exhibits neurite outgrowth-promoting activity, underscoring its role in facilitating the extension of neuronal processes. Additionally, CNTN4 may play a key role in synaptogenesis, the process of forming functional connections between neurons. The interaction of CNTN4 with PTPRG suggests potential involvement in modulating signaling pathways or cellular adhesion during neural development. The diverse functions attributed to Contactin-4, including neurite outgrowth promotion and potential contributions to synaptogenesis, highlight its importance in orchestrating intricate processes crucial for the establishment of functional neural circuits.

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.

  • Reconstitution Calculator

  • Dilution Calculator

  • Specific Activity Calculator

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
