CY3-223+

If you mean the fluorescent dye family Cy3 (often written as Cy3 and variants like CY3-223+), here’s a quick intro. If you’re referring to a different CY3-223+ (e.g., a gene, reagent code, or course), please share more context.
- What it is: A cyanine-based fluorescent dye used to label biomolecules (antibodies, nucleic acids, proteins) for detection in fluorescence applications.
- Spectral properties: Excitation around 550 nm; emission around 570 nm (orange-red fluorescence). Bright and broadly compatible with common fluorescence instruments.
- How it’s used: Conjugated to probes via NHS ester, amine, or click chemistries; employed in microscopy, flow cytometry, FISH, and microarrays.
- Pros/cons: High brightness and compatibility with standard filters; moderate photostability and potential photobleaching; sensitivity to pH and environmental conditions; always use appropriate protection from light and avoid reducing/bleaching environments.
- Practical notes: Check the supplier’s product sheet for exact spectral data and optimal conjugation chemistry; “223+” may indicate a specific salt/variant rather than a general property.
If you provide a vendor or context, I can tailor the intro to that CY3-223+ variant.

CY3-223+ isn’t a universal package code; the exact package depends on the manufacturer and the device type (IC, sensor, LED, etc.). To identify it, check the manufacturer's datasheet or catalog for CY3-223+. If unavailable, provide the full part number, vendor, and specs so I can determine the specific package (SOP, QFN, DIP, SOT, etc.) and footprint.

I can’t identify a single manufacturer from the code CY3-223+ alone. Please provide one of the following:
- the product category (e.g., sensor, relay, motor, connector)
- a link to the product page or a photo of the label/datasheet
With that, I can name the maker and describe what kind of company it is (e.g., a multinational electronics manufacturer vs. a specialized supplier).

CY3-223+ is a cationic cyanine dye used as a fluorescent label in biotechnology. Common applications include labeling nucleic acids (DNA/RNA probes and primers), immunofluorescence and FISH, flow cytometry and cell imaging (confocal, wide-field), fluorescence-based biosensors and diagnostic assays, and microarrays.
