Background

PAP protein plays a dual regulatory role in cell growth, demonstrating contrasting effects depending on the specific growth factor involved. In fibroblasts, it acts as a positive regulator by enhancing PDGFA-stimulated cell growth. However, simultaneously, it acts as a negative regulator by inhibiting the mitogenic effect of PDGFB. This protein exerts a fine-tuned control over cell growth, potentially influencing cellular responses to different growth factors and contributing to the overall balance and regulation of cell proliferation. The intricate interplay between PAP protein and growth factors like PDGFA and PDGFB highlights the complexity of cellular growth regulation and the importance of understanding the specific molecular mechanisms involved.

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
