CD28 Protein, Rat (HEK293, Fc)

Cat. No.: HY-P74310
SDS COA Handling Instructions

CD28 Protein activates T-cells, promoting cell proliferation, cytokine production, and T-cell survival. It collaborates with TCR/CD3 ligation and CD40L costimulation to boost IL4 and IL10 production in T-cells. CD28 Protein forms a disulfide-linked homodimer and interacts with DUSP14. It also binds to CD80/B7-1 and CD86/B7-2/B70, and interacts with GRB2 (By similarity). CD28 Protein, Rat (HEK293, Fc) is the recombinant rat-derived CD28 protein, expressed by HEK293 , with C-hFc labeled tag.

It collaborates with TCR/CD3 ligation and CD40L costimulation to boost IL4 and IL10 production in T-cells. CD28 Protein forms a disulfide-linked homodimer and interacts with DUSP14.

CD28 Protein, Rat (HEK293, Fc) is the recombinant rat-derived CD28 protein, expressed by HEK293 , with C-hFc labeled tag.

Background

CD28 Protein plays a crucial role in T-cell activation by inducing cell proliferation, cytokine production, and promoting T-cell survival. It works in conjunction with TCR/CD3 ligation and CD40L costimulation to enhance the production of IL4 and IL10 in T-cells. CD28 Protein forms a homodimer through disulfide-linkage and interacts with DUSP14. Additionally, it binds to CD80/B7-1 and CD86/B7-2/B70, and has an interaction with GRB2 (By similarity).

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)
× = ×
C1   V1   C2   V2

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
