ELISA
This version of ELISA uses one round of antibodies.
What is direct ELISA?
This substance binds proteins and other positively charged particles in the cytosol.
What is eosin?
The most abundant cell in mammalian blood.
What is the red blood cell (erythrocyte)?
"We followed the steps from some handout."
Problem: Failure to describe/cite the protocol specifically.
Edit: "We followed the procedure outlined in SDS-PAGE protocol (Rockland Immunochemicals, 2018)."
The largest blood vessel in the human body.
What is the aorta?
A form of ELISA valued for its increased sensitivity and versatility.
What is indirect ELISA?
This dye binds negatively charged structures, like the nucleus.
What is hematoxylin?
This white blood cell has a multi-lobed nucleus.
What is a neutrophil?
"Our results prove that nicotine impedes phagocytosis."
Error: Experiments do not prove.
Edit: "Our results support the possibility that nicotine impedes phagocytosis."
The largest animal ever known to have existed.
What is the blue whale?
These are tested alongside patient samples to avoid false negatives.
This category of fixatives is prone to producing artifacts.
What is a precipitating fixative?
The collection of blood sample for analysis.
What is a venipuncture?
"We follow the BIOS 312 SDS-PAGE protocol with no deviations."
Problem: Tense. A procedure section should be written in the past tense.
Edit: "We followed the BIOS 312 SDS-PAGE protocol with no deviations."
The largest known animal cell.
What is the ostrich egg?
The purpose of negative controls in ELISA.
What is to avoid false positives?
The heart tissue samples we used in lab were mechanically supported by this substance. (This substance allowed the tissue to be thinly sliced without losing its structure).
What is paraffin wax?
In healthy human blood, leukocytes make up this percentage of white blood cells.
What is about 40%?
"ELISA uses antibodies that bind antigens, which are present in the sample."
Problem: Ambiguous syntax. The referent for the "which" clause is unclear.
Edit: "In ELISA, antibodies bind antigens present in the sample."
The extant animal with the largest known brain.
What is the sperm whale?
The region of a primary antibody where a secondary antibody binds.
What is the constant region (Fc)?
What is lithium carbonate (LiCO3)?
This cell is the progenitor of platelets.
What is the megakaryocyte?
"Immunostaining is a crucial technique for identifying proteins in cells or tissue samples because it detects the presence of specific proteins."
Problem: Circular reasoning, wordiness
Rewrite: "Immunostaining is a technique used to detect specific proteins in cells or tissue samples."
The largest known colonial organism in the world.
What is Pando?
