Method Name | Advantage | Disadvantage |
---|---|---|
Stain removal technologies | ||
MELC (Toponome imaging systems) |
Detects hundreds of proteins and high resolution | The multiprobe image is limited to a single microscopic medium-to-high power field and high cost |
SIMPLE | Easy to perform by whole-slide scanner and can be labeled primary antibodies from same species | Up to 12 biomarkers |
IBEX | Allows over 65 biomarkers to detect and compatible with over 250 commercial antibodies | Not commercialized and few studies |
Fluorophore inactivation technologies | ||
MxIF | Up to 60 biomarkers | Time-consuming and relatively expensive |
CycIF | Use commonly reagents and instruments | Before the next staining, coverslip should be removed and time-consuming |
ChipCytometry | Detects unlimited number of biomarkers, long-storage samples, removes autofluorescence and instrument automaticity | Damage the tissue adherence and photobleachable dyes may generate weak signals during imaging processing |
Multiplexed signal amplification | ||
Multiplex modified hapten-based | Two-hour fast staining and cocktail antibodies are used in a single slide | Maximal four biomarkers can be labeled per slide and not applied widely |
TSA | Avoids antibody cross-reactivity and may realize an automated protocol | Nine biomarkers can be labeled per slide |
QDs | Removes autofluorescence and has much stronger signals | Big size relatively, has toxicity and limited nanocrystals |
DNA barcoding technologies | ||
DEI | Short-time staining and applies for most microscopy platforms | Lack of signal amplification, few studies |
CODEX | Allows 60 biomarkers labeled and can be imaged by conventional fluorescence microscopy, also keeps the morphology of normal and diseased tissues | Longer scanning and lack of signal amplification |
Immuno-SABER | High multiplexing, sensitivity and 5–180-fold signal amplification | Up to 10-plex and few publications |
DSP | No-damage staining protocol and performs high multiplexing image on FFPE samples | Chooses ROI manually and is not able to reconstruct images |
InSituPlex® | Good signal in low-expression antigen, 5.5 h workflow and relatively cheap | Few studies |
Mass cytometry | ||
IMC | Removes autofluorescence, reveals the quantity of proteins in subcellular level | Lack of signal amplification, the rate of image acquisition is slow and relatively low resolution in subcellular level |
MIBI | A large number of metal-antibodies can be labeled spectral overlap and high resolution | Time-consuming, instrument and metal-antibodies are expensive |
