Category: DNA Protocols: cDNA Library Protocols

Here, the DNA-RNA hybrids synthesized in Stage 1 are converted into full-length double-stranded cDNAs. The primers for synthesis of second-strand cDNA are created by RNase H, which introduces nicks into the RNA moiety of the cDNA-mRNA hybrids. E. coli DNA polymerase I extends the newly created 3'-hydroxyl termini, using the first-strand cDNA as a template. - [Read Construction of cDNA Libraries Protocol]

This protocol introduces a method for maintaining mammalian cell culture suitable for treatment with siRNA. Transfection of cultured cells with siRNAs (see Transfection of siRNA Duplexes into Mammalian Cells) and downstream analysis of the knockdown cells. - [Read Mammalian Cell Culture and Preparation of Cells for RNAi in 24-Well Plates Protocol]

Category: Cell Biology and Cell Culture: Cell Adhesion Protocols

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.

This protocol introduces the use of a liquid-filled wash chamber that separates unbound cells by gravity thereby eliminating uncontrolled shear forces and passage of adherent cells through a liquid/air interface. The cells are loaded with a fluorescent dye (6-carboxyfluorescein diacetate) for detection although other methods such as radioactive labels malabels may be used. This protocol is also useful for assaying molecules that promote or inhibit cell adhesion. - [Read Protocol for Measurement of Cell Adhesion Under Static Conditions]
