Background

CAP8A plays an indispensable role in the intricate process of biosynthesizing type 8 capsular polysaccharide (Cap8/CP8). As a putative chain-length regulator, its involvement is crucial in orchestrating the controlled assembly of the capsular polysaccharide structure. The enzymatic functions of CAP8A contribute significantly to the precise biosynthesis of Cap8/CP8, underscoring its importance in the intricate molecular machinery governing the formation and regulation of capsular polysaccharides, particularly in the context of type 8 structures.

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
