These are three types of RNAscope probes. The type of probe is indicated as follows:

Probe
for Manual Assays

LS Probe
for Leica Systems automated assays

VS Probe
for Ventana Systems automated assays

Species refers to the probe target species and implies that the probe is designed to the gene of the specified species. The species is typically identified by two letter designations such as "Hs" for Homo Sapiens, "Mm" for Mus musculus etc

This refers to the Official Gene Symbol as listed in the NCBI Database

This indicates the probe amplification channel denoted by C1, C2 or C3. RNAscope probes default to Channel 1 unless specified. This channel indicates the compatibility of the probes with different amplification systems and indicate which detection kits the probes would be compatible with.

C1 probes are compatible with all detection platforms

C2 probes are compatible only with the 2.5 HD Duplex Detection Kit and the Fluorescent Detection Kit

C3 channel probes are only compatible with the Fluorescent Detection Kit
