Background

The CA12 protein, also known as Carbonic Anhydrase 12, plays a pivotal role in the reversible hydration of carbon dioxide. This enzyme catalyzes the conversion of carbon dioxide to bicarbonate ions and protons, contributing significantly to essential physiological processes. Its enzymatic activity is integral to the regulation of pH levels, aiding in the maintenance of acid-base balance within the body. As a member of the carbonic anhydrase family, CA12 is involved in the fundamental biochemical reactions related to carbon dioxide transport and buffering in tissues, underscoring its importance in cellular homeostasis.

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.

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
