B7-H4 Protein, Human (HEK293, Fc)

Cat. No.: HY-P7640
Handling Instructions

B7-H4 Protein, Human (HEK293, Fc) may participate in negative regulation of cell-mediated immunity in peripheral tissues. Cell-associated B7-H4 could also inhibit T cell response. B7-H4 acts as a morphogenic factor for cancer cells[1][2][3].

Stored at -20°C. After reconstitution, it is stable at 4°C for 1 week or -20°C for longer. It is recommended to freeze aliquots at -20°C or -80°C for extended storage.


Room temperature in continental US; may vary elsewhere.


Human B7-H4 mRNA is expressed in spleen, lung, and thymus. B7-H4 expression can be induced on T cells, B cells, monocytes, and DC after in vitro stimulation. [1].
Mouse B7-H4 transcript is detected in the heart, lung, liver, skeletal muscle, kidneys, and testis but not in brain and spleen[1].
B7-H4 is a cancer promoter and a potentially important therapeutic target[3].

  • Reconstitution Calculator

  • Dilution 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)
× = ×
