Complement C3 Protein, Human (HEK293, His)

Cat. No.: HY-P702819
Handling Instructions

Complement C3 protein activates the complement system, playing a central role in both classical and alternative pathways. C3b binds covalently to cell surface carbohydrates or immune aggregates, while C3a acts as an inflammatory mediator, inducing neutrophil chemoattraction and promoting smooth muscle contraction, increased vascular permeability, and histamine release. The shorter isoform of C3a stimulates B-cells. Complement C3 Protein, Mouse (HEK293, His) is the recombinant mouse-derived Complement C3 protein, expressed by HEK293 , with C-His labeled tag. The total length of Complement C3 Protein, Mouse (HEK293, His) is 1639 a.a., with molecular weight of 65-68 kDa & 110-115 kDa & 165-180 kDa, respectively.

Background

Complement C3/C3a protein plays a pivotal role in the activation of the complement system, being the central reaction in both classical and alternative pathways. Following activation, C3b can bind covalently to cell surface carbohydrates or immune aggregates through its reactive thioester. C3a, derived from the proteolytic degradation of complement C3, acts as a local inflammatory mediator, inducing neutrophil chemoattraction and promoting smooth muscle contraction, increased vascular permeability, and histamine release from mast cells and basophilic leukocytes. Additionally, the shorter isoform of C3a exhibits B-cell stimulatory activity.

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
