| KIF21B

Kinesin family member 21B (KIF21B), also known as kinesin-4, is a protein encoded by the KIF21B gene. It is part of the kinesin family of motor proteins. This gene encodes a member of the kinesin superfamily. Kinesins are ATP-dependent microtubule-based motor proteins that are involved in the intracellular transport of membranous organelles. Single nucleotide polymorphisms in this gene are associated with inflammatory bowel disease and multiple sclerosis. Alternatively spliced transcript variants encoding multiple isoforms have been observed for this gene.
 

| 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	2.57	1.98	1.41	1.22	0.78	0.45	0.27	0.09
Corrected OD	2.48	1.89	1.32	1.13	0.69	0.36	0.18	-

 

| Repeatability

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

| Recovery

The recovery of Human KIF21B 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)	96-108	105

 

| Linearity

Samples were spiked with high concentrations of Human KIF21B and diluted with Universal Diluent to produce samples with values within the range of the assay.

 

		Tissue Homogenates(n=4)	Cell Lysates(n=4)
1 : 2	Range (%)	84-95	90-110
	Average (%)	90	96
1 : 4	Range (%)	89-103	105-116
	Average (%)	94	108
