| TBX21

T-box transcription factor TBX21, also called T-bet (T-box expressed in T cells), is a protein that is encoded by the TBX21 gene. Though being for long thought of only as a master regulator of type 1 immune response, T-bet has recently been shown to be implicated in development of various immune cell subsets and maintenance of mucosal homeostasis.
 

| 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	2.31	1.59	0.99	0.6	0.4	0.27	0.19	0.07
Corrected OD	2.24	1.52	0.92	0.53	0.33	0.2	0.12	-

 

| Repeatability

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

| Recovery

The recovery of Human TBX21 spiked at three different levels in samples throughout the range of the assay was evaluated in various matrices.

 

Sample Type	Range(%)	Average Recovery(%)
Cell Culture Supernates(n=8)	94-108	103

 

| Linearity

Samples were spiked with high concentrations of Human TBX21 and diluted with Universal Diluent to produce samples with values within the range of the assay.
