The FAM caspase binding assay kits from ATCC Corporation can be used to determine amounts of active caspases in cells. The FAM-labeled caspase inhibitor can freely diffuse into the cell. Active caspase irreversibly binds the inhibitor. Upon washing the cells, the amount of fluorescence is proportional to the amount of active caspase in the cell. FAM-LETD-fmk (catalog no. 30-1306) is used to detect caspase 8 and FAM-LEHD-fmk (catalog no. 30-1308) is used for caspase 9. - [Read Fam Caspase 8 and 9 Binding Assay for Embryos Protocol]

Hybridization is carried out in conventional aqueous solvents at a temperature well below the predicted melting temperature. Nonspecific hybrids are then removed by washing at high stringency in buffers containing quaternary salts. Tetramethylammonium chloride (TMACl) is used with probes that are 14-50 nucleotides in length, whereas tetraethylammonium chloride (TEACl) is used with longer oligonucleotides. - [Read Hybridization of Oligonucleotide Probes in Aqueous Solutions Protocol]
Protocol for immunohistochemistry with AP-Conjugated (NBT/BCIP). Protocol extensively blocks slides, further diluting the primary antibody, lengthening the incubation and washing time, using a simple AP-conjugated secondary at high dilution and use a slow long development with the most powerful IHC development, NBT/BCIP. Includes: Single AP stainiing and Double AP staining. - [Read Immunohistochemistry with AP-Conjugated (NBT/BCIP) Protocol]
Describes the basic principles of in situ hybridization and advantages and disadvantages of different methodologies that can be used. Includes: Probe Selection; Probe Generation; Probe Labels; Fixation of Tissue; Hybridization and Washing; Control Procedures. - [Read In situ Hybridization]
Many proteins and molecules promote cell adhesion including several cell surface carbohydrate binding proteins. Cell adhesion measurements on 96-well microtiter plate format are difficult due to the shear forces generated by washing the wells. The protocol here introduces the use of a liquid-filled wash chamber that separates unbound cells by gravity. This eliminates uncontrolled shear forces and passage of adherent cells through a liquid/air interface. John L.

Protocol details the preparation of fluorescently labeled target samples and hybridization of these samples to a microarray of Agilent inkjet-deposited presynthesized oligonucleotides. The procedure requires a minimum of 3 µg of purified total RNA as starting material. Includes: cDNA Synthesis; Fluorescent cRNA Synthesis; cRNA Precipitation and Cleanup; cRNA Quantification; Hybridization; Washing. - [Read Microarray Protocol for Agilent Inkjet-Deposited Presynthesized Oligo Arrays]
Protocol for the purification of DNA recovered from agarose and polyacrylamide gels by anion-exchange chromatography. Fragments of DNA recovered from agarose gels are sometimes poor templates or substrates in subsequent enzymatic reactions. This problem can be solved by binding the DNA to a positively charged matrix, such as DEAE-Sephadex or DEAE-Sephacel, in buffers of low ionic strength. After washing the matrix, the DNA is eluted by raising the strength of the buffer. - [Read Purification of DNA Recovered Anion-exchange Chromatography Protocol]

Electrocompetent bacteria are prepared by growing cultures tomid-log phase, washing the bacteria extensively at low temperature,and then resuspending them in a solution of low ionic strengthcontaining glycerol. DNA is introduced during exposure of thebacteria to a short high-voltage electrical discharge.
A protocol for the selection of Phage Antibodies using Immobilized Antigen. This method describes the selection of antibodies from bacteriophage antibody libraries that recognize a specific antigen. The phage display library of antibody-displaying phage particles is exposed to antigen attached to a solid substrate (Nunc Immuno™ tubes). The phage particles with affinity for antigen bind to the immobilized antigen and are selected from the library of phage expressing antibodies.
Unlike spherical phage, such as T4 and λ, which have roughly equal weight ratios of protein to DNA, filamentous phage have about six times more protein than DNA; the protein therefore contributes substantially to the absorption spectrum.
