PHPT1 Protein, Human (His)

Cat. No.: HY-P75975
COA Handling Instructions

The PHPT1 protein acts as a phosphohistidine phosphatase, catalyzing the dephosphorylation of phosphohistidine residues. This unique enzymatic activity makes PHPT1 a regulator of histidine phosphorylation events, suggesting that it is involved in signaling pathways or cellular processes that are critical for phosphohistidine modification. PHPT1 Protein, Human (His) is the recombinant human-derived PHPT1 protein, expressed by E. coli , with N-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)
× = ×

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
