Erythrose-4-phosphate Analysis Service
Online InquiryAbout Erythrose-4-phosphate
Erythrose 4-phosphate is a phosphate of the monosaccharide erythrose. It is an intermediate of the pentose phosphate pathway and Calvin cycle.
In addition, it is also a precursor for the biosynthesis of aromatic amino acids tyrosine, phenylalanine and tryptophan. It is used in the first step of the shikimate pathway. At this stage, phosphoenolpyruvate and 4-phosphate erythroside react in a reaction catalyzed by DAHP synthase to form 3-deoxy-D-arabinoheptulonic acid-7-phosphate (DAHP).
Its chemical formula is C4H9O7P, and CAS number is 585-18-2.
MS-based technical means can realize the qualitative and quantitative analysis of erythrose-4-phosphate.

Technical Route of Targeted Metabolomics of Erythrose-4-phosphate
Sample Requirements
| Sample type |
| Plants, yeasts, microorganisms, etc. Serum, plasma, urine, bile, bile acid, etc. Cells, liver, brain tissue and other animal tissues and feces, etc. There is no restriction on plant varieties. For varieties with special requirements or rare varieties, please contact our staff for more information. |
| Sample demand |
| Plant root / stem / leaf / fruit / seed > 200 mg fresh weight, freeze-dried sample > 0.5 g Cells / microorganisms / cell supernatant / culture medium supernatant: the number of cells or bacteria > 107, supernatant > 2 ml Serum / plasma / urine / ruminal fluid / cerebrospinal fluid / amniotic fluid and other homogeneous liquid samples > 200 µl. (Hemolysis should be avoided. Cerebrospinal fluid can be as low as 100 µl.) Animal tissue / feces related samples > 200 mg / sample For other sample types, please consult technical support or sales. |
| Sample mixed and repeat |
| In order to ensure the accuracy of the samples and reduce systematic errors during sampling, it is necessary to select more than 3 materials with the same condition for each sample. ※ The same condition refers to the same period, basically the same phenotype, and the same part. It is recommended that prepare more than 6 biological replicates. |
| Storage and transportation |
| Quick-frozen preservation with liquid nitrogen can minimize the leakage time of plant samples at room temperature, and store it at -80°C. Dry ice transportation (about 3~4 kg dry ice is consumed every day, please use sufficient dry ice for transportation). |
