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 for preparation of denaturing polyacrylamide gels containing formamide.The inclusion of formamide in sequencing gels eliminates secondary structure in the DNA during electrophoresis. Formamide gels are particularly useful and almost a necessity when sequencing DNA templates with a G/C content >55%. - [Read Preparation of Denaturing Polyacrylamide Gels Containing Formamide Protocol]
Human embryonic stem cells are a valuable resource for research and cell replacement therapy but are notoriously cumbersome to culture. Bhatia and colleagues show that an increased dose of basic fibroblast growth factor eliminates the need for feeder laye - [Read Simplifying hESC culture]
Simple method for growing Neurospora and for isolation of DNA that may be performed in two days from start to finish. The growth of mycelia in Petri plates eliminates the need for large numbers of flasks when growing many cultures for DNA isolation. - [Read Ultra-Fast Method of DNA Extraction from Neurospora Protocol]
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]
