| LDH-A

Lactate dehydrogenase A (LDHA) is an enzyme encoded by the LDHA gene and belongs to the lactate dehydrogenase family. It is a monomer of Lactate dehydrogenase, which exists as a tetramer. LDHA is found in most somatic tissues, though predominantly in muscle tissue and tumors, and belongs to the lactate dehydrogenase family. It has also been shown that LDHA plays an important role in the development, invasion and metastasis of malignancies. Mutations in LDHA have been linked to exertional myoglobinuria.
 

| Typical data

As the OD values of the standard curve may vary according to the conditions of the actual assay performance (e.g. operator, pipetting technique, wash technique or temperature effects), the operator should establish a standard curve for each test. Typical standard curve and data are provided below for reference only.

 

Concentration (ng/mL)	20	10	5	2.5	1.25	0.625	0.312	0
OD	2.15	1.46	0.87	0.6	0.39	0.28	0.21	0.09
Corrected OD	2.06	1.37	0.78	0.51	0.3	0.19	0.12	-

 

| Repeatability

Intra-assay Precision (Precision within an assay)：CV% < 10%; Inter-assay Precision (Precision between assays)：CV% < 10%
 

| Recovery

The recovery of Mouse LDH-A spiked at three different levels in samples throughout the range of the assay was evaluated in various matrices.

 

Sample Type	Range(%)	Average Recovery(%)
Serum(n=8)	84-103	98
Plasma(n=8)	92-105	102
Tissue Homogenates(n=8)	96-108	105

 

| Linearity

Samples were spiked with high concentrations of Mouse LDH-A and diluted with Universal Diluent to produce samples with values within the range of the assay.

 

		Serum(n=4)	Plasma(n=4)	Tissue Homogenates(n=4)
1 : 2	Range (%)	85-95	88-98	90-110
	Average (%)	91	95	96
1 : 4	Range (%)	89-103	87-108	105-115
	Average (%)	94	98	108
