Assay of Cyclic AMP in Lysates of Cells - http://www.signaling-gateway.org/data/cgi-bin/ProtocolFile.cgi/afcs_PP00000015.pdf?pid=PP00000015

Category: Signalling Signal Transduction Protocols

Protocol allows you to measure the content of cyclic adenosine 3',5'-monophosphate (cyclic AMP or cAMP) in splenic B lymphocytes (B cells) in an enzyme-linked immunoassay. This protocol utilizes acetylation of cAMP to improve sensitivity and reduce interference. Protocol includes information on: how to determine cAMP, calculations and reagents and materials. - [Read Assay of Cyclic AMP in Lysates of Cells]

CYP1A1-Inducing Potency and Cytotoxicity Test in the HEPA-1 Mouse Hepatoma Cell Line - http://embryo.ib.amwaw.edu.pl/invittox/prot/112.htm

Category: Pharmacology and Toxicology Protocols: Cytotoxicity Protocols: Liver Toxicity Assays Protocols

This bioassay utilizes cultured Hepa-lclc7 (Hepa-1) mouse hepatoma cells to assess the CYPlA1-inducing potency or cytotoxicity of pure test chemicals or environmental samples. In the Hepa-l induction test , the CYPlA1-inducing potency of the test sample is detected as increased aryl hydrocarbon hydroxylase (AHH) and 7-ethoxyresorufin O-deethylase (EROD) activities. - [Read CYP1A1-Inducing Potency and Cytotoxicity Test in the HEPA-1 Mouse Hepatoma Cell Line]

Directed Yeast Two Hybrid Screening for MEKK1 Interaction Partners Protocol - http://www.natureprotocols.com/2007/01/22/directed_yeast_two_hybrid_scre.php

Category: Yeast Protocols: Yeast Two-Hybrid Systems Protocols

Protocol utilizes the Y190 yeast strain, that characteristically turns from white to red during growth due to ademutation. Baits were subcloned into the pAS1cyh2 vector, and Preys subcloned into pACT2. - [Read Directed Yeast Two Hybrid Screening for MEKK1 Interaction Partners Protocol]

FIXATION and DNA Staining for Cell Cycle Analysis - http://www.biotech.iastate.edu/facilities/CELLHYB/CCAnalysis.htm

FIXATION and DNA Staining for Cell Cycle Analysis Protocol. This method of DNA staining utilizes ethanol to fix the cells and permeabilize the membrane, which allows the dye (Propidium Iodide) to enter the cells. Propidium Iodide (PI) is a DNA-binding fluorochrome that intercalates in the double-helix. Ribonuclease-A is used to eliminate the staining of double-stranded RNA. - [Read FIXATION and DNA Staining for Cell Cycle Analysis]

Laser Capture Microdissection (LCM) - http://cgap-mf.nih.gov/Protocols/Microdissection/LCM.html

Category: Primary Cell Isolation and Culture Protocols: Laser Capture Microdissection Protocols

LCM utilizes an infrared laser integrated into a standard microscope. A transparent cap is attached to a thermoplastic transparent membrane which lies directly on the surface of a routinely prepared tissue section on a glass slide. The investigator examines the tissue section microscopically and activates the laser when the desired cells underlie the target. This in turn activates the membrane with subsequent binding and procurement of the cells of interest. - [Read Laser Capture Microdissection (LCM)]
