| GZMM

Granzyme M is a protein that encoded by the GZMM gene.Human natural killer (NK) cells and activated lymphocytes express and store a distinct subset of neutral serine proteases together with proteoglycans and other immune effector molecules in large cytoplasmic granules. These serine proteases are collectively termed granzymes and include 4 distinct gene products: granzyme A, granzyme B, granzyme H, and Met-ase, also known as granzyme M.Granzyme M cleaves peptide substrates after methionine, leucine, and norleucine. Physiological substrates include EZR, alpha-tubulins and the apoptosis inhibitor BIRC5/Survivin. Promotes caspase activation and subsequent apoptosis of target cells.
 

| 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 (pg/mL)	1000	500	250	125	62.5	31.25	15.62	0
OD	2.22	1.56	0.92	0.63	0.42	0.25	0.18	0.01
Corrected OD	2.14	1.48	0.84	0.55	0.34	0.17	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 GZMM spiked at three different levels in samples throughout the range of the assay was evaluated in various matrices.

 

Sample Type	Range(%)	Average Recovery(%)
Serum(n=8)	84-101	94
Plasma(n=8)	92-106	103
Tissue Homogenates(n=8)	96-108	105

 

| Linearity

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

 

		Serum(n=4)	Plasma(n=4)	Tissue Homogenates(n=4)
1 : 2	Range (%)	84-95	88-95	90-110
	Average (%)	91	93	96
1 : 4	Range (%)	89-103	87-108	105-114
	Average (%)	94	98	107
