C1s-A subcomponent Protein, Mouse (HEK293, His)

Cat. No.: HY-P75463
COA Handling Instructions

C1s-A subcomponent protein, a serine protease, is pivotal in the classical complement system pathway. Partnering with C1q and C1r, it forms C1, initiating complement activation. Activated by C1r, C1s can subsequently trigger downstream components C2 and C4, influencing the complement system cascade. C1s-A subcomponent Protein, Mouse (HEK293, His) is the recombinant mouse-derived C1s-A subcomponent protein, expressed by HEK293, with C-His labeled tag. The total length of C1s-A subcomponent Protein, Mouse (HEK293, His) is 673 a.a., with molecular weight of ~76.6 kDa.

Activated by C1r, C1s can subsequently trigger downstream components C2 and C4, influencing the complement system cascade.

Background

C1s-A subcomponent protein is a serine protease that plays a crucial role in the classical pathway of the complement system. It associates with C1q and C1r to form C1, the initiating component of this pathway. Upon activation by C1r, C1s becomes capable of activating downstream components C2 and C4, contributing to the cascade of events in the complement system.

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.

  • 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
