ARF3 Protein, Human (His)

Cat. No.: HY-P75583
COA Handling Instructions

ARF3 protein, a GTP-binding allosteric activator of cholera toxin, plays a role in protein trafficking and vesicle dynamics in the Golgi apparatus. Beyond toxin activation, ARF3 interacts with PRKCABP, participating in diverse cellular processes. It also associates with PI4KB and NCS1/FREQ at the Golgi complex, emphasizing its role in crucial molecular interactions for cellular functions. ARF3 Protein, Human (His) is the recombinant human-derived ARF3 protein, expressed by E. coli , with N-His labeled tag. The total length of ARF3 Protein, Human (His) is 181 a.a., with molecular weight of ~23 kDa.

Background

ARF3, a GTP-binding protein, acts as an allosteric activator of the catalytic subunit of cholera toxin, an ADP-ribosyltransferase. Beyond its role in toxin activation, ARF3 is implicated in protein trafficking, exerting potential influence on vesicle budding and uncoating within the Golgi apparatus. This multifaceted protein interacts with PRKCABP, highlighting its involvement in various cellular processes. Additionally, ARF3 associates with PI4KB and NCS1/FREQ at the Golgi complex, further emphasizing its participation in molecular interactions crucial for cellular functions.

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
