Common Pitfalls
Translation Traps (for Russian speakers)
- Avoid translating as 'лизат' as it's a direct transliteration with no established meaning. Use 'лизированный материал', 'клеточный экстракт', or 'лизант' (scientific term).
Common Mistakes
- Using it as a verb (e.g., 'to lysate the cells' - the verb is 'to lyse').
- Treating it as a countable noun (e.g., 'three lysates' is acceptable in lab jargon but 'samples of lysate' is more standard).

Frequently Asked Questions
No. The verb is 'to lyse'. 'Lysate' is the noun for the resulting material.
Almost never. It is a highly technical term specific to life sciences and medicine.
They are often used synonymously in lab jargon. However, 'lysate' specifically implies the material was obtained by lysing (breaking open) cells, while 'extract' can have broader methods of preparation.
It is pronounced LY-sate, with a long 'i' sound like in 'lyse' or 'light', and 'sate' rhyming with 'gate'.
