Human PCYOX1 ELISA Kit: Your Questions Answered

Prenylcysteine oxidase 1 (PCYOX1) , also known as prenylcysteine lyase (PCL1) , is a peroxisomal enzyme that catalyzes the oxidative cleavage of prenylcysteine — a post-translationally modified amino acid generated during the prenylation of proteins such as Ras, Rho, and Rab GTPases. By degrading prenylcysteine, PCYOX1 regulates the cellular pool of prenylated proteins, impacting signal transduction, membrane trafficking, and cytoskeletal dynamics. PCYOX1 dysregulation has been implicated in atherosclerosis, neurodegeneration, and cancer [0†L9-L10][0†L25].

Abbkine's Human Prenylcysteine oxidase 1 (PCYOX1) ELISA Kit (KTE61281) provides researchers with a reliable tool for quantifying this important peroxisomal enzyme in human samples [0†L6-L8]. Here are answers to the most common questions about this kit and PCYOX1 detection.

What is the detection principle of this PCYOX1 ELISA kit?

This kit employs a two-site sandwich ELISA to quantitate PCYOX1 in samples. An antibody specific for PCYOX1 has been pre-coated onto a microplate. When you add standards and samples, any PCYOX1 present binds to the immobilized antibody. After removing any unbound substances, a biotin-conjugated antibody specific for PCYOX1 is added to the wells. After washing, Streptavidin conjugated Horseradish Peroxidase (HRP) is added. Following a wash to remove any unbound avidin-enzyme reagent, a substrate solution is added and color develops in proportion to the amount of PCYOX1 bound. The color development is stopped and the intensity of the color is measured [0†L11-L21].

What sample types can I use?

The kit is validated for serum, plasma, cell culture supernatants, and other biological fluids [0†L21-L22]. This flexibility makes it suitable for various experimental systems, from cell culture models to clinical research samples.

What are the key features and benefits?

How should I store and handle the kit?

• Unopened kit: Store at 2–8°C [0†L41-L42]
• Opened kit: Follow protocol-specific storage instructions [0†L42-L43]
• Shipping: Gel pack with blue ice [0†L43]

Critical handling tips from the manufacturer:

• Do not mix components from different kit lots or use reagents beyond the kit expiration date [0†L33-L35]
• Allow all reagents to warm to room temperature for at least 30 minutes before opening [0†L35-L36]
• Pre-rinse the pipet tip with reagent; use fresh pipet tips for each sample, standard, and reagent to avoid contamination [0†L36-L37]
• Mix thoroughly — recommended using a low-frequency oscillator or slight hand shaking every 10 minutes [0†L38-L40]
• Run samples and standards in duplicate or triplicate [0†L40-L41]
• Unused wells must be kept desiccated at 4°C in the sealed bag provided [0†L37-L38]

What applications is this kit suitable for?

This kit is designed for research use only — not for human or clinical diagnosis [0†L44-L45]. Applications include:

• Prenylcysteine metabolism and protein prenylation research
• Atherosclerosis and cardiovascular disease studies
• Neurodegenerative disease research
• Signal transduction (Ras, Rho, Rab GTPase pathways)
• Cancer biology (prenylation inhibitors)
• Drug development (PCYOX1-targeted therapeutics)

What is the biological significance of PCYOX1?

PCYOX1 sits at the crossroads of post-translational modification and cellular metabolism:

• Prenylated proteins (Ras, Rho, Rab) are critical for cell signaling, membrane trafficking, and cytoskeletal organization
• PCYOX1 degrades prenylcysteine, regulating the pool of prenylated proteins
• PCYOX1 dysregulation is linked to atherosclerotic plaque formation, neuronal dysfunction, and tumor progression

What's included in the kit?

A complete, ready-to-use kit.
