sufficient Protocols

Category: Cytogenetics Protocols

This CGH Protocol is used for DNA of good quality when available in sufficient amounts. We usually do replicate hybridizations using samples labeled "inversely" (reversing the label for test and normal DNA's). If appreciable artifact occurs, then alternative labels are tried. - [Read CGH of Direct Labeled Test DNA vs Normal DNA Protocol]

The use of Ferbach flasks is an ideal method to amplify the cells and virus inoculum for the bioreactor. The method is also very practical for producing sufficient amounts of various proteins for feasibility studies using HyQ© SFX-Insect™ medium. The large surface area in this vessel enables sufficient aeration and, therefore, the cells, when they reach high density, are not oxygen depleted. - [Read Culturing of Insect Cells and Production of Baculovirus Expressed Recombinant Proteins in 2.8 Liter]

Category: C. elegans Protocols: C. elegans Fixing Protocols

Protocol for fixation and permeabilization of C. elegans. Protocol works for all stages except dauers (which won't open) and hypoclorite-treated eggs (which disintegrate). Luckily, hypochlorite treatment and fixation are by themselves sufficient to open eggs. - [Read Fixation and Permeabilization of C. elegans Protocol]

Category: Viral Culture and Isolation Protocols: Viral Culture Protocols

A crude lysate gel assay can be performed to roughly quantitate the DNA in lysates. This is often a valuable time saving step to determine if the phage yield is sufficient to warrant continuing the procedure. - [Read Gel Assay to Determine DNA Content of Phage Lysates Protocol]

Category: Nucleic Acid Purification Protocols: DNA Isolation Protocols: Genomic DNA Isolation Protocols

Protocol for isolation of DNA from mammalian cells grown in 96-well microtiter plates. Each well yields sufficient genomic DNA for several standard PCRs or for analysis in a single lane of a Southern hybridization. - [Read Isolation of DNA from Mammalian Cells Grown in 96-well Microtiter Plates Protocol]

Category: Cell Organelle Protocols: Subcellular Fractionation Protocols: Peroxisome Isolation Protocols

To isolate peroxisomes from Saccharomyces cerevisiae of a quality sufficient for in vitro import studies, we optimized the conditions for cell growth and for cell fractionation. Stability of the isolated peroxisomes was monitored by catalase latency and sedimentability of marker enzymes. - [Read Peroxisomes in Saccharomyces cerevisiae]

Category: Signalling Signal Transduction Protocols

This protocol provides a sufficient sample for several determinations of cAMP using the acetylation protocol. The method chosen for measuring the content of cyclic adenosine 3',5'-monophosphate (cyclic AMP or cAMP) in splenic B lymphocytes (B cells) is an enzyme linked immunoassay system. Protocol includes information on: Treatment of Cells and Preparation of Extracts; Reagents and Materials. - [Read Preparation of B-Lymphocyte Lysates for Cyclic AMP Determination]

Category: Signalling Signal Transduction Protocols

Protocol provides a method of achieving a sufficient sample for several determinations of cAMP using Amersham’s acetylation protocol. Protocol includes information on: Treatment of Cells and Preparation of Extracts; Reagents and Materials. - [Read Preparation of B-Lymphocyte Lysates for Cyclic AMP Determination for Dual Ligand Screen]

Category: Signalling Signal Transduction Protocols

Protocol provides a method for acheiving a sufficient sample for several determinations of cAMP. The protocol described for measuring the content of cyclic adenosine 3',5'- monophosphate (cyclic AMP or cAMP) in cardiac myocytes is an enzyme-linked immunoassay system. Protocol includes information on: Treatment of Cells and Preparation of Extracts; Use of Environmental Chamber; Reagents and Materials. - [Read Preparation of Myocyte Lysates for Cyclic AMP Determination]

Category: Signalling Signal Transduction Protocols

The protocol provides a method to achieve a sample sufficient for one determination of cAMP using the acetylation protocol. The protocol describes the method used for measuring the content of cyclic adenosine 3',5'- monophosphate (cyclic AMP or cAMP) in RAW 264.7 cells using an enzyme-linked immunoassay system. Information included in the protocol: Treatment of Cells and Preparation of Extracts; Reagents and Materials. - [Read Preparation of RAW 264.7 Lysates for Cyclic AMP Determination]

Category: Cell Biology and Cell Culture: Cell Cycle Protocols

This method works well to assess cell cycle distribution of whole cell populations. This method can also be used to assess the cell cycle distribution of GFP transfected cells however, the EtOH step is generally not sufficient to keep GFP in the cell. - [Read Preparing Cells for PI/FACS (cell cycle) Analysis Protocol]

Category: Plant Biology Protocols

Alfalfa is an outcrossing species, cultivars consist of populations rather than individual homozygous or inbred lines. After only two cycles of self-pollination, severe inbreeding depression eliminates selfed individuals from populations. To obtain sufficient plant material of relative genetically uniformity (these plants will still necessarily be heterozygous) for experimental purposes, it may be necessary to propagate a single individual or clone. - [Read Vegetative Propagation of Alfalfa by Stem Cuttings]
