What is Virus Titer Converter?

Virus titer unit converter — Convert viral vector titers across units: TU/mL (Transducing Units, functional transduction), GC/mL = vg/mL (Genome Copies, ddPCR/qPCR quantification), PFU/mL (Plaque Forming Units), IFU/mL (Infectious Units). Applies vector-specific (AAV/LV/Ad) functional-to-physical ratios.

When should I use Virus Titer Converter?

(1) Convert GC titer (from vector core) to TU titer for MOI calculation (2) Estimate functional TU titer from lentivirus p24 ELISA (physical particle count) (3) Compare AAV qPCR vg/mL ↔ infectious units (typically 1 IFU ≈ 100–1000 vg) (4) Compare published PFU values with in-house batch GC

Can you show me an example of Virus Titer Converter?

Example 1) AAV9 from vector core at 1×10¹³ vg/mL → estimated TU → AAV typical vg:TU ~10⁴:1 (cell-line dependent) → Estimated TU ≈ 1×10⁹ TU/mL Example 2) Lentivirus 5×10⁸ TU/mL → estimated GC → LV typical GC:TU ~100–1000:1 → GC ≈ 5×10¹⁰ – 5×10¹¹ GC/mL

Virus Titer Converter

Convert per-mL and per-µL concentration units only within the same assay basis

same-basis per µL × 1000 = per mL

Only mL and µL units within the same assay basis are converted. No cross-basis equivalence is inferred.

Tool Guide

Definition

A converter limited to per-mL and per-µL concentration units within one assay basis. Distinct biological bases are BLOCKED.

Purpose

Change only the volume denominator of a native titer value while preserving lot, assay, and basis identity.

How to Use

Enter a value and choose input and output units. If their assay bases differ, the tool displays MIXED_ASSAY_BASIS_BLOCKED instead of a result.

Examples

Example: 2 GC/µL equals 2,000 GC/mL. Selecting GC/mL to TU/mL blocks the conversion.
