LDH Assay Kit / Lactate Dehydrogenase Assay Kit (Colorimetric) (CAT#: CB-P144-K) Datasheet

Product Type
Lactate dehydrogenase (LDH) analysis kit (colorimetric) can quantitatively detect LDH activity in various samples (such as serum or plasma, tissue, cells and culture medium).
In the LDH analysis protocol, LDH reduces NAD to NADH and then interacts with a specific probe to produce color (maximum OD = 450 nm). The kit can directly detect 1-100 mU/mL LDH in the sample. The assay is fast, convenient and sensitive.

Figure 1 Kinetic profiles of approx 0.5 mU of a sample of pure LDH (Positive Control) and 2 μL frozen human serum using buffer as a background control.

Figure 2 NADH Standard Curve.

Figure 3 Cellular necrosis was measured as LDH release after cisplatin treatment for 24 h and 48 h using ab102526. The release of LDH was apparently increased at 24 and 48 h after cisplatin treatment.
