| TGM3

Protein-glutamine gamma-glutamyltransferase E is an enzyme that is encoded by the TGM3 gene.Transglutaminases are enzymes that catalyze the crosslinking of proteins by epsilon-gamma glutamyl lysine isopeptide bonds. While the primary structure of transglutaminases is not conserved, they all have the same amino acid sequence at their active sites and their activity is calcium-dependent. The protein encoded by this gene consists of two polypeptide chains activated from a single precursor protein by proteolysis. The encoded protein is involved the later stages of cell envelope formation in the epidermis and hair follicle.
 

| 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	0.62	0.31	0
OD	2.15	1.7	1.2	0.77	0.43	0.23	0.14	0.04
Corrected OD	2.11	1.66	1.16	0.73	0.39	0.19	0.1	-

 

| Repeatability

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

| Recovery

The recovery of Human TGM3 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)	92-105	102
Cell Culture Supernates(n=8)	96-108	105

 

| Linearity

Samples were spiked with high concentrations of Human TGM3 and diluted with Universal Diluent to produce samples with values within the range of the assay.

 

		Tissue Homogenates(n=4)	Cell Culture Supernates(n=4)
1 : 2	Range (%)	88-96	90-110
	Average (%)	92	96
1 : 4	Range (%)	87-108	105-115
