Assay Background

The beta thymosins are a family of highly conserved polar 5 kDa peptides originally thought to be thymus hormones. Further studies demonstrated that beta thymosins are ubiquitous; they have been found in a variety of tissues and cell lines. The high-est concentrations have been detected in spleen, thymus, lung, and peritoneal macrophages.
Thymosin beta4 binds monomeric actin in a 1:1 complex acting as an actin buffer, preventing polymerisation into actin filaments but supplying a pool of actin monomers when needed by the cell. Changes in the expression of thymosin β4 appear to be related to the differentiation of cells. Thymosin β4 is detected outside of cells in blood plasma and wound fluid. Several biological effects are attributed to thymosin β4, like induction of metallo proteinases, chemotaxis, angiogenesis and inhibition of inflammation as well as inhibition of bone marrow stem cell proliferation.


Quality Control
We recommend the use of external controls for internal quality control, if possible.
Control samples should be analysed with each run. Results, generated from the analysis of control samples, should be evaluated for acceptability using appropriate statistical methods. The results for the samples may not be valid if within the same assay one or more values of the quality control sample are outside the acceptable limits.
Reference range
The values in healthy people are strongly age-dependent. Newborn show the highest, and from the age of 20 the serum values are falling. We recommend each laboratory to establish its own reference range for different age-ranges.

Assay Procedure


This ELISA is designed for the quantitative determination of thymosin ß4 (Tß4) in serum and thymus preparations. The test principle is based on a competition between antigen in the sample or standards and the antigen coated on the wells of microplate. A peroxidase-conjugated antibody is used for detection and quantification, and tetramethylbenzidine (TMB) as a peroxidase substrate. The enzymatic reaction is terminated by acidic stop solution. The intensity of the colour is inversely proportional to the concentration of Tß4. A dose response curve of absorbance unit (optical density, OD at 450 nm) vs. concentration is generated using the values obtained from standard. Tß4, present in the samples, is determined directly from this curve.
