| KAL

Kallistatin is a protein that in humans is encoded by the SERPINA4 gene.Kallistatin consists of three folded ß segments and eight helical structures and contains two functional domains, an active site and a heparin-binding site.Kallistatin signals through several receptors, including integrin ß3, lipoprotein receptor-related protein 6 ( LRP6 ), nucleolin, and Krüppel-like factor 4 ( KLF4 ).
 

| 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)	2000	1000	500	250	125	62.5	31.25	0
OD	2.52	1.96	1.38	0.97	0.55	0.31	0.19	0.08
Corrected OD	2.44	1.88	1.3	0.88	0.47	0.23	0.11	-

 

| Repeatability

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

| Recovery

The recovery of Human KAL 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)	84-101	95
Plasma(n=8)	92-105	102
Tissue Homogenates(n=8)	97-108	105

 

| Linearity

Samples were spiked with high concentrations of Human KAL 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 (%)	84-95	88-96	90-110
	Average (%)	92	93	96
1 : 4	Range (%)	89-101	87-108	105-115
	Average (%)	94	98	108
