New areas, new requirements how bioassay
meets gene therapy and CAR-T technologies?
According to Lisa Finn, an environmental project manager with the USACE Galveston District s Navigation Branch, the contract requires collection and analyses of sediment including elutriate samples; grain-size analyses; suspended particulate phase bioassays
; solid phase bioassays
and bioaccumulation assessments.
Differences in toxicity caused by spinosad between semi-synthetic and natural diet bioassays
may simply reflect differences in the bioassay
methods and species tested.
utilized 700-mL glass jars in which a mixture of 18 g of vermiculite (5- to 10-mm particle size range) and 6 g of Eucalyptus regnans F.
The red flour beetle (RFB) was selected as a test organism with which to develop a rapid, inexpensive, and sensitive bioassay
for evaluation of organophosphate decontamination.
This is the first demonstration that gold nanoparticles can be grown when entrapped in silica and the first report of sol-gel-based inks being used to produce a dipstick-based bioassay
Users can create and recall automatic scanning patterns for different plate configurations, AutoZONE is ideal for applications including multi-zone bioassay
plate analysis (commonly 36 and 64 zone plates) and Single Radial Immunodiffusion assay plates.
Because the mouse bioassay
requires euthanizing many animals, and results are not available for several hours, new diagnostic methods are needed.
CEKCL was tested using the brine shrimp lethality bioassay
, followed by evaluation of antihypertensive activity on anaesthetized rats.
We developed and validated a yeast-based bioassay
to measure androgen bioactivity in clinical samples, including human serum, for the detection of androgen-like and antiandrogenic compounds (9).
This general bioassay
for phase II enzyme induction can employ different cell lines, and is advocated by the National Institutes of Health for use as an effective screening tool to locate natural cancer chemopreventive agents.
Pettis and colleagues at ARS's Bee Research Laboratory, in Beltsville, Maryland, devised a do-it-yourself bioassay
that determines, within 6 hours, whether a hive's mite population is fully resistant, approaching resistance, or still vulnerable to chemical treatment.
Our objective is to develop an in vivo bioassay
to test water borne chemicals for endocrine disruption at the molecular level.
To accomplish the bioassay
, proliferating interstitial cells are labeled with BrdU by injecting BrdU into the gastrovascular cavity of the animal (n = 10).
is the first step used to investigate the possible involvement of allelopathy (Foy, 1999).
