CheKine™ Micro Creatine Kinase (CK) Activity Assay Kit — FAQ for Clinical and Metabolic Research

CheKine™ Micro Creatine Kinase (CK) Activity Assay Kit: Your Questions Answered

Creatine Kinase (CK) (EC 2.7.3.2) mainly exists in the heart, muscle, brain, and other tissues[reference:50]. It reversibly catalyzes the phosphorylation reaction between creatine and ATP, playing an important role in energy metabolism, muscle contraction, and ATP regeneration[reference:51]. CK is an important indicator for clinical diagnosis of heart and brain diseases[reference:52].

Abbkine's CheKine™ Micro Creatine Kinase (CK) Activity Assay Kit (KTB1012) provides a simple method for detecting CK activity in various samples[reference:53]. Here are answers to the most common questions about this kit.

What is the detection principle?

The kit measures CK activity by monitoring the reverse reaction — the phosphorylation of creatine by ATP to form phosphocreatine and ADP. The activity is determined by measuring the rate of ATP consumption or product formation, typically through a coupled enzyme system that generates a colorimetric or fluorometric signal.

What sample types can I use?

The kit is validated for:

• Animal tissues
• Cultured cells
• Serum[reference:54]

What's the detection format?

• 96-well plate format[reference:55]
• Requires a UV-Transparent Microplate for detection[reference:56]

How should I prepare samples?

• Detailed sample preparation methods are provided in the protocol[reference:57]
• Follow the instructions carefully for each sample type
• Ensure complete homogenization for tissue samples

How should I store and handle the kit?

• Storage: Store at –20°C and protect from light upon receipt[reference:58]
• Shelf life: 6 months from receipt[reference:59]
• Shipping: Gel pack with blue ice[reference:60]

Critical handling tips:

• Do not mix or substitute reagents or materials from other kit lots or vendors[reference:61]
• Run samples and standards in duplicate or triplicate
• Ensure all reagents are at the appropriate temperature before starting

What applications is this kit suitable for?

This kit is designed for research use only — not for human or clinical diagnosis[reference:62]. Applications include:

• Muscle physiology research (muscle contraction, exercise physiology)
• Cardiovascular research (heart disease models, cardiac function)
• Neuroscience (brain energy metabolism, neurodegenerative diseases)
• Metabolism research (energy homeostasis, ATP regeneration)
• Drug development (modulators of energy metabolism)
• Toxicology (cardiotoxicity and neurotoxicity screening)

Why measure creatine kinase activity?

CK activity is a biomarker of tissue damage — elevated CK levels in serum indicate muscle, heart, or brain injury. In research settings, CK activity measurements help:

• Assess muscle damage in exercise and injury models
• Monitor cardiac health in cardiovascular disease models
• Evaluate neurotoxicity in brain injury studies
• Study energy metabolism in metabolic disorders

What's included in the kit?

A complete, ready-to-use kit.
