| Hpt;HP

Haptoglobin (abbreviated as Hp) is the protein that is encoded by the HP gene.[5][6] In blood plasma, haptoglobin binds with high affinity to free hemoglobin released from erythrocytes, and thereby inhibits its deleterious oxidative activity. Compared to Hp, hemopexin binds to free heme.The haptoglobin-hemoglobin complex will then be removed by the reticuloendothelial system (mostly the spleen).
 

| 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)	10	5	2.5	1.25	0.625	0.312	0.156	0
OD	2.66	1.57	0.79	0.45	0.26	0.18	0.15	0.05
Corrected OD	2.61	1.52	0.74	0.4	0.21	0.13	0.1	-

 

| Repeatability

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

| Recovery

The recovery of Human Hpt;HP 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)	82-102	97
Plasma(n=8)	90-104	100

 

| Linearity

Samples were spiked with high concentrations of Human Hpt;HP and diluted with Universal Diluent to produce samples with values within the range of the assay.

 

		Serum(n=4)	Plasma(n=4)
1 : 2	Range (%)	81-96	82-99
	Average (%)	93	90
1 : 4	Range (%)	89-104	87-108
	Average (%)	93	97
