| GAP-43

Growth Associated Protein 43 (GAP43) is a protein encoded by the GAP43 gene. GAP43 is called a "growth" or "plasticity" protein because it is expressed at high levels in neuronal growth cones during development[6] and axonal regeneration, and it is phosphorylated after long-term potentiation and after learning. GAP43 is a crucial component of the axon and presynaptic terminal. Its null mutation leads to death within days after birth, due to axon pathfinding defects.
 

| 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	2.45	1.46	0.89	0.57	0.39	0.28	0.23	0.09
Corrected OD	2.36	1.37	0.8	0.48	0.3	0.19	0.14	-

 

| Repeatability

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

| Recovery

The recovery of Mouse GAP-43 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	104

 

| Linearity

Samples were spiked with high concentrations of Mouse GAP-43 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 (%)	91	96
1 : 4	Range (%)	89-102	105-114
	Average (%)	93	107
