CTLA-4 Protein, Canine (HEK293, Fc)

Cat. No.: HY-P75321
Data Sheet Handling Instructions

CTLA-4 protein inhibits T-cell responses as a critical negative regulator, with a stronger affinity for CD80 and CD86 than CD28. This affinity allows CTLA-4 to effectively suppress T-cell activation and regulate immune responses, maintaining a delicate equilibrium in T-cell-mediated immunity. CTLA-4 Protein, Canine (HEK293, Fc) is the recombinant canine-derived CTLA-4 protein, expressed by HEK293 , with C-hFc labeled tag. The total length of CTLA-4 Protein, Canine (HEK293, Fc) is 161 a.a., with molecular weight of ~40.1 kDa.

Description

CTLA-4 protein inhibits T-cell responses as a critical negative regulator, with a stronger affinity for CD80 and CD86 than CD28. This affinity allows CTLA-4 to effectively suppress T-cell activation and regulate immune responses, maintaining a delicate equilibrium in T-cell-mediated immunity. CTLA-4 Protein, Canine (HEK293, Fc) is the recombinant canine-derived CTLA-4 protein, expressed by HEK293 , with C-hFc labeled tag. The total length of CTLA-4 Protein, Canine (HEK293, Fc) is 161 a.a., with molecular weight of ~40.1 kDa.

Background

CTLA-4 protein functions as a critical inhibitory receptor, playing a pivotal role as a major negative regulator in T-cell responses. The distinguishing feature of CTLA-4 lies in its significantly stronger affinity for its natural B7 family ligands, CD80 and CD86, compared to the affinity of their corresponding stimulatory coreceptor, CD28. This heightened affinity enables CTLA-4 to effectively counterbalance and suppress T-cell activation, contributing to the intricate regulation of immune responses. The dynamic interplay between CTLA-4 and its ligands underscores its significance in fine-tuning the immune system and maintaining a delicate equilibrium between activation and inhibition in T-cell-mediated immunity.

  • 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
