CheKine™ Soil Free Amino Acid (S-FAA) Content Assay Kit (Micro Method)

Catalog Number: KTB4063-S
Sample Type: Soil
Assay Method: Micro Method

Product Overview

The CheKine™ Soil Free Amino Acid (S-FAA) Content Assay Kit (Micro Method) is a core detection tool specifically designed for the accurate quantification of free amino acid content in soil samples. This kit employs the classic ninhydrin colorimetric method, enabling high-sensitivity and high-specificity detection of S-FAA in soil by measuring the characteristic absorption peak at 570 nm. It is applicable to research areas such as soil nitrogen cycle studies, agricultural ecological analysis, and environmental science research.

Assay Principle

The α-amino group of free amino acids in soil reacts with hydrindantin (ninhydrin hydrate) under appropriate conditions to generate a blue-purple compound, which exhibits a characteristic absorption peak at a wavelength of 570 nm. The content of free amino acids in the soil sample can be accurately calculated by measuring the absorbance value.

Core Components

• Extraction Buffer
• ReagentⅠ
• ReagentⅡ
• Standard (5 mg)

Technical Parameters

• Detection Range: 1.25 - 20 μmol/mL
• Sensitivity: 1.25 μmol/mL
• Storage Conditions: Store protected from light at 4°C; valid for 6 months
• Shipping Conditions: Shipped with ice packs (blue ice)

Features and Advantages

• Optimized for soil samples with high extraction efficiency
• Simple operation procedure and short experimental cycle
• Excellent kit stability and high reproducibility
• Available in 48T and 96T specifications to meet different throughput needs

Application Background

Soil free amino acids are a vital component of the soil nitrogen pool, accounting for approximately 15%–60% of total nitrogen. They serve as a direct nitrogen source for plants and are key substrates for microbial metabolism. Their dynamic content directly affects soil nitrogen cycling efficiency, microbial community structure, and plant nutritional status. This kit provides a reliable and efficient quantitative tool for research in these related fields.
