| GSK-3β

Glycogen synthase kinase-3 beta, (GSK-3 beta), is an enzyme that is encoded by the GSK3B gene. Abnormal regulation and expression of GSK-3 beta is associated with an increased susceptibility towards bipolar disorder.Glycogen synthase kinase-3 (GSK-3) is a proline-directed serine-threonine kinase that was initially identified as a phosphorylating and an inactivating agent of glycogen synthase. Two isoforms, alpha (GSK3A) and beta, show a high degree of amino acid homology.[5] GSK3B is involved in energy metabolism, neuronal cell development, and body pattern formation. It might be a new therapeutic target for ischemic stroke.
 

| 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	2.4	1.69	1.29	0.9	0.61	0.43	0.31	0.09
Corrected OD	2.31	1.6	1.2	0.81	0.52	0.34	0.22	-

 

| Repeatability

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

| Recovery

The recovery of Mouse GSK-3β 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)	83-101	96
Cell Lysates(n=8)	92-105	100

 

| Linearity

Samples were spiked with high concentrations of Mouse GSK-3β 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	85-96
	Average (%)	91	93
1 : 4	Range (%)	89-103	87-108
	Average (%)	95	98
