Sulforhodamine B

Sulforhodamine B is a chemistry topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Sulforhodamine B rather than just read about it. In short: Sulforhodamine B or Kiton Red 620 (C27H30N2O7S2) is a fluorescent dye with uses spanning from laser-induced fluorescence (LIF) to the quantification of cellular proteins of cultured cells. This red solid dye is very water-soluble.

Key takeaways

  • Sulforhodamine B belongs to chemistry; place it in that map before memorising details.
  • Learn the definition first, then one example that makes the definition concrete.
  • Connect Sulforhodamine B to a quantity you can measure, compute or draw — that is where exam questions come from.
  • Reproduce the core statement of Sulforhodamine B from memory before moving on to harder problems.

Reference excerpt

Sulforhodamine B or Kiton Red 620 (C27H30N2O7S2) is a fluorescent dye with uses spanning from laser-induced fluorescence (LIF) to the quantification of cellular proteins of cultured cells. This red solid dye is very water-soluble.

Spectroscopy The dye has maximal absorbance at 565 nm light and maximal fluorescence emission at 586 nm light. It does not exhibit pH-dependent absorption or fluorescence over the range of 3 to 10.

Applications Sulforhodamine B is often used as a membrane-impermeable polar tracer or used for cell density determination via determination of cellular proteins (cytotoxicity assay).

Worked examples

Example 1 — a first encounter with Sulforhodamine B

Start with the simplest possible case. Write down what Sulforhodamine B claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In chemistry, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Sulforhodamine B before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Sulforhodamine B ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Sulforhodamine B

In research
Sulforhodamine B appears in chemistry research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry
Engineering practice reuses Sulforhodamine B in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom
Sulforhodamine B is common in secondary-school and first-year university syllabi. It links to neighbouring topics Benzenesulfonates, Diethylamino compounds, Rhodamine dyes, so understanding it makes those chapters shorter.
In everyday life
Look for Sulforhodamine B outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
