Used to measure nickel (Ni) enzyme activity in plant tissues, this ELISA kit helps researchers study nickel's role in plant metabolism, especially in urease-related processes. It is commonly applied in agricultural research to assess nickel deficiency or toxicity in crops, evaluate soil nutrition, and improve fertilizer strategies. The kit supports high-throughput analysis, making it useful in breeding programs and environmental stress studies where nickel homeostasis affects plant health and yield.
