Semaphorin-4B/SEMA4B Protein, Human (HEK293, His)

Cat. No.: HY-P71284
Handling Instructions

Semaphorin-4B (SEMA4B) Protein, functioning as an inhibitor, crucially modulates axonal extension by providing localized signals that specify territories as inaccessible for growing axons. Semaphorin-4B/SEMA4B Protein, Human (HEK293, His) is the recombinant human-derived Semaphorin-4B/SEMA4B protein, expressed by HEK293 , with C-6*His labeled tag.

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)
× = ×
C1   V1   C2   V2

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
