IMF-102-01-0005-en	What is the labelling difference between direct and indirect immunofluorescence?	Direct uses a labelled primary antibody; indirect uses a labelled secondary antibody that binds the primary antibody.	Integrated Medical Foundations; chapter 102, TTS module 1; https://theisegoria.github.io/medical-textbook/integrated-medical-foundations-expanded-english.md; module SHA256 at export: 05c02b4f6b6873cb9603943095d179690208bbc5fba415091ae7609d6669fac6; editorial review pending	imf lang::en chapter::102 module::102-01 review::pending
IMF-102-01-0006-en	What does a positive staining control test?	Whether the staining system can detect its target under the assay conditions; it does not alone prove every sample signal is specific.

IMF-102-01-0010-en	How do conventional TEM and SEM differ in what they image?	TEM uses electrons transmitted through thin sections to show internal ultrastructure; SEM uses surface-associated signals to show surface topography.	Integrated Medical Foundations; chapter 102, TTS module 1; https://theisegoria.github.io/medical-textbook/integrated-medical-foundations-expanded-english.md; module SHA256 at export: 05c02b4f6b6873cb9603943095d179690208bbc5fba415091ae7609d6669fac6; editorial review pending	imf lang::en chapter::102 module::102-01 review::pending
IMF-102-01-0011-en	Why should an immortalised cell line be authenticated rather than trusted by its label?	Misidentification and contamination can occur; the label does not establish the identity of the cells actually used.	Integrated Medical Foundations; chapter 102, TTS module 1; https://theisegoria.github.io/medical-textbook/integrated-medical-foundations-expanded-english.md; module SHA256 at export: 05c02b4f6b6873cb9603943095d179690208bbc5fba415091ae7609d6669fac6; editorial review pending	imf lang::en chapter::102 module::102-01 review::pending
IMF-102-01-0012-en	Does an organoid automatically reproduce an entire organism?	No. It models selected architecture and interactions while omitting other systemic conditions.

IMF-102-01-0016-en	Why is a treatment-responsive housekeeping protein unsuitable as a Western blot loading control?	Its abundance changes with treatment, so normalisation to it can distort the apparent target change.	Integrated Medical Foundations; chapter 102, TTS module 1; https://theisegoria.github.io/medical-textbook/integrated-medical-foundations-expanded-english.md; module SHA256 at export: 05c02b4f6b6873cb9603943095d179690208bbc5fba415091ae7609d6669fac6; editorial review pending	imf lang::en chapter::102 module::102-01 review::pending
IMF-102-01-0017-en	What does flow-cytometry compensation correct?	Spectral spillover of fluorescence into other detection channels; it does not establish biological marker specificity.

IMF-102-01-0019-en	Do twenty technical wells from one donor constitute twenty independent biological replicates?	No. They assess technical variability within that donor; the biological donor count remains one.	Integrated Medical Foundations; chapter 102, TTS module 1; https://theisegoria.github.io/medical-textbook/integrated-medical-foundations-expanded-english.md; module SHA256 at export: 05c02b4f6b6873cb9603943095d179690208bbc5fba415091ae7609d6669fac6; editorial review pending	imf lang::en chapter::102 module::102-01 review::pending
IMF-102-01-0020-en	Why validate a finding with methods based on different physical principles?	Independent methods can have different artefacts, so agreement reduces reliance on a single method's assumptions without proving certainty.	Integrated Medical Foundations; chapter 102, TTS module 1; https://theisegoria.github.io/medical-textbook/integrated-medical-foundations-expanded-english.md; module SHA256 at export: 05c02b4f6b6873cb9603943095d179690208bbc5fba415091ae7609d6669fac6; editorial review pending	imf lang::en chapter::102 module::102-01 review::pending
IMF-102-01-0021-en	What does an assay blank help account for?	Background contributed by reagents and the measurement container; it does not reproduce every interference in a biological sample.

IMF-102-01-0022-en	Within the linear Beer-Lambert range, what happens to absorbance if concentration doubles while path length and molar absorptivity remain fixed?	Absorbance doubles. This inference assumes the same absorbing species and valid linear measurement conditions.	Integrated Medical Foundations; chapter 102, TTS module 1; https://theisegoria.github.io/medical-textbook/integrated-medical-foundations-expanded-english.md; module SHA256 at export: 05c02b4f6b6873cb9603943095d179690208bbc5fba415091ae7609d6669fac6; editorial review pending	imf lang::en chapter::102 module::102-01 review::pending
IMF-102-01-0023-en	Why can turbidity invalidate a simple absorbance-to-concentration conversion?	Scattering contributes to loss of transmitted light, so the signal is not explained by absorption alone.
