Fluoro Sarcosine

Product Description

Introduction

Sarcosine is natural amino acid that is an important intermediate in the metabolism of choline. Sarcosine is an important component of proteins and plays a significant role in metabolic processes of living cells as a source of serine, creatine, purines and glutathione etc. Sarcosine is present in food sources like legumes, eggs, ham, turkey etc. It is used in a variety of industrial applications such as manufacturing of tooth paste and biodegradable surfactants. Sarcosine was recently reported to activate prostate cancer cells and as a possible marker for prostate cancer progression to metastasis(1). It is also used in adjunctive treatment for Schizophrenia (2) and depression (3).

Cell Technology’s Fluoro Sarcosine assay provides a reliable, sensitive fluorimetric method for the quantification of sarcosine in biological samples.
The Fluoro Sarcosine detection kit utilizes a non-fluorescent detection reagent, which is reduced via an enzyme-coupled reaction in the presence of sarcosine. A sarcosine standard curve is generated to quantify sarcosine in the samples.

Key Benefits

• Easy to Use – No Wash Assay.
• Detection of Sarcosine in cells, serum, tissue extracts.
• Easy to Use 96-well Fluorescent Plate reader readout.

Reaction

Sarcosine + non-fluorescent detection reagent+ Enzyme Mix —–> fluorescent analog

Excitation: 530-570nm and Emission at 590-600

Table 1: We conducted spike and recovery experiments to estimate % recovery of sarcosine. Serum was spiked with sarcosine with the concentrations mentioned in the table above. The samples were processed as described in section IX of the protocol.

Table 2: We conducted spike and recovery experiments to estimate % recovery of sarcosine. Cell lysates were spiked with sarcosine with the concentrations mentioned in the table above. The samples were processed as described in section VIII: Mammalian Cell Preparation.

Table 3: Serum samples were diluted 1:5 in standard curve diluent. Jurkat and Daudi cells were prepared as described in the protocol. After the final wash cells were adjusted to 1X106 cells/mL in standard curve diluent. Sarcosine was measured as described in the protocol.

Figure 1. Sarcosine standard curve was generated as described in the protocol. R2= 0.998
