Glycosylated RNA research
GlycoRNA is read differently from a chemical modification: what is detected is the glycan attached to the RNA, not a change in a base. Arraystar covers it with screening, sequencing and blotting under one line.
01What is being asked
GlycoRNA work asks whether RNA carries a glycan, on which molecules, and whether the signal changes between biological conditions. The readout targets the glycan, so the methods are different from those used for base-level chemical modification.
That difference is worth stating plainly: a modification method reads a change in a nucleotide, while a glycoRNA method reads a sugar on an RNA. The two are not interchangeable, and a study about glycosylation should be designed on its own terms.
In practice the work splits into screening, sequencing and direct detection of the glycoRNA population, and the three are normally used together on the same material.
02The three routes
GlycoRNA Array
Array-based screening of glycosylated RNA targets, for comparing conditions across many molecules.
Screeningarray SEQUENCEGlycoRNA Sequencing (small RNA)
Sequencing of glycosylated small RNA: which short RNA species carry the glycan signal.
Sequencingsmall RNA DETECTGlycoRNA Blotting
Lectin-based detection of glycoRNAs as a population: how much there is, and at which sizes.
Whole-classblot03What the blotting route reports
The blotting service detects endogenous glycoRNAs following RNA separation and membrane transfer, using the natural glycan-binding specificity of lectins. Because the lectin recognises the glycan rather than the RNA sequence, the assay does not depend on artificial metabolic labeling such as Ac4ManNAz, and it avoids the prolonged metabolic incubation that labeling requires.
The readout is the glycoRNA population of the sample rather than one selected molecule: the overall glycosylated signal, its abundance and its molecular-size pattern. Cultured cells, tissues and biofluids are all workable starting material.
- RNA extraction from the sample.
- Gel electrophoresis to separate the RNA by size.
- Transfer to a membrane and crosslinking.
- Lectin probing of the glycan.
- Signal detection and comparison between samples.
- Native-state detection: endogenous glycoRNA is detected without artificial metabolic labeling.
- No labeling step: the workflow omits prolonged metabolic incubation and complex labeling procedures.
- Size information: the blot shows molecular-size patterns, not just an intensity.
- Broad sample compatibility: cultured cells, tissues and biofluids.
- Reads the population, not a target list: the blot does not need a candidate molecule to be chosen first — what is detected is the glycoRNA present in the sample as a class.

05FAQ
Is glycosylation a chemical modification of RNA?
No. GlycoRNA carries a glycan attached to the RNA rather than a changed nucleotide, so it is not read by the chemistry used for base-level modifications. It is handled as its own line, with array screening, sequencing and lectin-based detection of the glycoRNA population.
Does the blotting assay need metabolic labeling?
No. Detection uses lectins, whose natural glycan-binding specificity recognises the glycan directly, so labeling compounds such as Ac4ManNAz are not required. That also removes the prolonged metabolic incubation that labeling-based workflows need before the RNA can be analyzed.
What sample types are accepted?
Cultured cells, tissues and biofluids. Total RNA extracted from those materials is the usual starting point, and it is also what the array and sequencing routes work from, so the routes can share one preparation of the same material rather than asking for separate aliquots of it.
What does a blotting result show?
The glycoRNA population of the sample: overall abundance and molecular-size patterns, compared between conditions. Because the lectin reads the glycan rather than a chosen target, the blot does not need a candidate molecule to be selected first, and it reports the class as a whole.
Which RNA class does the sequencing route cover?
Glycosylated small RNA. Length class decides the library route, and this line covers the small RNA side, so the species list stays inside that class. A study working on miRNA-scale and other short glycoRNAs therefore reads them in the class they belong to.
