TRACP-5b Detection Service

TRACP-5b is a biochemical marker of osteoclast activity and number. Its serum level reflects the degree of osteolytic bone metastasis and also reflects the tumor burden in the bone environment. Therefore, serum TRACP-5b level is a biomarker of bone resorption and bears clinical applicability in the diagnosis and treatment of metabolic and pathological bone diseases. Creative BioMart Biomarker is capable to provide our customers with superior TRACP-5B detection service, various detection methods ensuring high sensitivity for detecting biomarkers in different samples with different concentrations.

Introduction

Tartrate-resistant acid phosphatase (TRACP) is a member of the diverse lysosomal enzyme group and has two forms in the circulation: TRACP-5a and TRACP-5b. TRACP-5b is derived from osteoclasts. During bone resorption, osteoclasts secrete TRACP-5b, which produces reactive oxygen species to digest bone degradation products of the bone matrix in the microenvironment. Therefore, it is used as a marker of the activity and numbers of osteoclasts. When TRACP-5b is released into the circulation, it is hydrolyzed by proteases to form fragments that are excreted in the urine and metabolized in the liver. TRACP-5b has several characteristics: i) it is specific for osteoclast number and activity; ii) it is associated with traditional bone resorption collagen markers; iii) it responds rapidly and significantly to anti-resorptive therapy; iv) it has a prognostic value for predicting an increased risk of bone mineral density (BMD) and fracture risk. In addition, TRACP-5b has some advantages in analysis and pre-analysis, exceeding many collagen markers. i) Serum TRACP-5b activity has a lower CVa and CVi because of its small diurnal variation. Compared with NTX and CTX, TRACP-5b is almost unaffected by meals; ii) TRACP-5b is not affected by kidney and liver diseases. Unlike collagen markers, they accumulate at high levels when kidney function or liver function is impaired.
