Description

The Siglec-15 protein plays a critical role in cellular interactions, selectively binding to sialylated glycoproteins with affinity for sialic acid residues. Binding to TYROBP and HCST suggests involvement in complex signaling pathways. Siglec-15 Protein, Human (HEK293, His) is the recombinant human-derived Siglec-15 protein, expressed by HEK293 , with C-6*His labeled tag.

Background

The Siglec-15 Protein plays a crucial role in cellular interactions by selectively binding to sialylated glycoproteins, indicating a specific affinity for molecules with sialic acid residues. Additionally, Siglec-15 engages in molecular associations with TYROBP and HCST, suggesting its involvement in intricate signaling pathways. This ability to interact with key signaling partners underscores Siglec-15's potential significance in mediating immune responses and cellular communication. The specific recognition of sialylated glycoproteins highlights the protein's role in recognizing and responding to cell surface modifications, contributing to the complex network of cellular interactions.

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.

  • 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
