General description

Tyrosine (Tyr) is an aromatic amino acid that is a precursor of several important substrates such as catecholamine, thyroid hormone, and melanin pigment. A deficiency in enzymes such as homogentisic acid oxidase or phenylalanine 4-hydroxylase that degrade tyrosine result in rare, hereditary metabolic disorders.

Suitability

Suitable for the detection of tyrosine in a variety of biological samples.

Principle

The Tyrosine Colorimetric Assay Kit provides a simple assay for measuring tyrosine in biological samples (ranging from 5-75 nmole/well). Tyrosine is determined by measuring a colorimetric product with absorbance at 492 nm (A492) proportional to the amount of tyrosine present.

To explore the new mechanism of neuroprtection of monosialotetrahexosylganglioside and providing reliable theoretical foundation and experimental evidence for the emergency treatment and rehabilitation of cerebral ischemia/reperfusion injury. A rat model of cerebral ischemia/reperfusion injury was constructed and intervened with monosialotetrahexosylganglioside(5mg/kg)

MicroRNAs (miRNAs, miR) play a fundamental role in cerebral ischemia/reperfusion (I/R) injury. However, the role of miRNAs in toxic aldehyde and tyrosine accumulation is not fully elucidated. We constructed a cerebral I/R rat model and found that overexpression of miR-193
