DNA Molar Concentration Calculator (µg/mL → nM)
Mass-to-molar DNA conversion: nM = (µg/mL × 10⁶)/(Da-per-bp × bp) with 650 Da/bp dsDNA and 330 Da/nt ssDNA, plus µM, pmol/µL, total pmol, and molecules/µL via Avogadro. Warns about the µM-vs-nM 1000× slip. NEB NEBioCalculator / Promega BioMath derived. Educational use only.

Quick start
Call this tool from your code in three languages.
cURL
curl -X POST 'https://api.elysiatools.com/en/api/tools/molar-dna-concentration' \

| Name | Type | Required | Description |
|---|---|---|---|
| concentration | number | Yes | Mass concentration of the DNA sample. 1 µg/mL is numerically identical to 1 ng/µL. |
| dnaType | select | Yes | dsDNA averages 650 Da/bp; ssDNA averages 330 Da/nt (NEB convention). |
| lengthBp | number | Yes | Full length of the DNA molecule in base pairs (nt for ssDNA). |
| sampleVolumeUl | number | No | Volume of the sample in µL; enter 0 to skip the total-pmol calculation. |
| decimalPlaces | number |
MCP integration
Add this tool to your Model Context Protocol server so AI agents can list and call it.

}List available tools
After connecting to the SSE endpoint, list the exposed tools:
tools/list
{
"jsonrpc": "2.0",
"id": 1,
"method": "tools/list"
}Call this tool
Invoke the tool by its id, passing arguments built from its parameters:
tools/call
{
"jsonrpc": "2.0",
"id": 2,
"method": "tools/call",
"params": {
"name": "molar-dna-concentration",
"arguments": {
"concentration": 50,
"dnaType": "dsDNA",
"lengthBp": 1000,
"sampleVolumeUl": 100,
"decimalPlaces": 3
}
}
}Chain multiple tools in one session with a comma-separated toolId list, e.g. /mcp/sse?toolId=png-to-webp,jpg-to-webp,gif-to-webp (max 20).
