EphB4 Protein, Human (sf9, His-GST)

Cat. No.: HY-P73003
Handling Instructions

EphB4 protein is a receptor tyrosine kinase that binds to ephrin B ligand and initiates bidirectional signaling. Positive signaling regulates the rejection and separation of cells from EFNB2-expressing cells. EphB4 Protein, Human (sf9, His-GST) is the recombinant human-derived EphB4 protein, expressed by Sf9 insect cells , with N-His, N-GST labeled tag.

Description

EphB4 protein is a receptor tyrosine kinase that binds to ephrin B ligand and initiates bidirectional signaling. Positive signaling regulates the rejection and separation of cells from EFNB2-expressing cells. EphB4 Protein, Human (sf9, His-GST) is the recombinant human-derived EphB4 protein, expressed by Sf9 insect cells , with N-His, N-GST labeled tag.

Background

EphB4 protein, a receptor tyrosine kinase, engages in promiscuous binding to transmembrane ephrin-B family ligands located on adjacent cells, initiating contact-dependent bidirectional signaling. The downstream pathway originating from the receptor is termed forward signaling, while the signaling pathway downstream of the ephrin ligand is referred to as reverse signaling. Collaborating with its cognate ligand, EFNB2, EphB4 is intricately involved in regulating cell adhesion and migration. Moreover, EphB4 assumes a central role in heart morphogenesis, angiogenesis, and the remodeling and permeability of blood vessels. The forward signaling mediated by EPHB4 is instrumental in controlling cellular repulsion and segregation from EFNB2-expressing cells.

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
