| ACVA

Activin A(ACVA) is a member of the TGF-β superfamily, a large family of more than 3 structurally related proteins. Activins have many functions， including roles in cell proliferation, differentiation, apoptosis,metabolism, homeostasis, immune response, wound repair,and endocrine function. Activin A signaling is similar to that of other TGF-β superfamily members. It binds to the activin Type II receptor (ActR) to form an isomeric receptor complex.
 

| 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)	2000	1000	500	250	125	62.5	31.25	0
OD	2.67	2.05	1.48	0.97	0.67	0.42	0.27	0.09
Corrected OD	2.58	1.96	1.39	0.88	0.58	0.33	0.18	-

 

| Repeatability

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

| Recovery

The recovery of Mouse ACVA 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	96
Plasma(n=8)	92-105	102
Cell Culture Supernates(n=8)	96-108	105

 

| Linearity

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

 

		Serum(n=4)	Plasma(n=4)	Cell Culture Supernates(n=4)
1 : 2	Range (%)	84-95	88-96	90-110
	Average (%)	91	93	96
1 : 4	Range (%)	89-103	88-108	105-115
	Average (%)	94	97	108
