| KLF2

Krüppel-like Factor 2 (KLF2), also known as lung Krüppel-like Factor (LKLF), is a protein that is encoded by the KLF2 gene on chromosome 19. It is in the Krüppel-like factor family of zinc finger transcription factors, and it has been implicated in a variety of biochemical processes in the human body, including lung development, embryonic erythropoiesis, epithelial integrity, T-cell viability, and adipogenesis.
 

| 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	2.4	1.77	1.11	0.7	0.45	0.3	0.2	0.07
Corrected OD	2.33	1.7	1.04	0.63	0.38	0.23	0.13	-

 

| Repeatability

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

| Recovery

The recovery of Human KLF2 spiked at three different levels in samples throughout the range of the assay was evaluated in various matrices.

 

Sample Type	Range(%)	Average Recovery(%)
Tissue Homogenates(n=8)	84-101	96
Cell Lysates(n=8)	92-105	102
Cell Culture Supernates(n=8)	98-108	107

 

| Linearity

Samples were spiked with high concentrations of Human KLF2 and diluted with Universal Diluent to produce samples with values within the range of the assay.

1 : 2	Range (%)	84-95	88-96	92-110
	Average (%)	91	93	98
1 : 4	Range (%)	89-103	87-108	105-115
