High performance liquid affinity chromatography (HPLAC) is a useful procedure to investigate he interactions between carbohydrate binding protein and their ligands. Technical requirements are similar to conventional HPLC. HPLAC can screen and separate natural ligands from complex biological mixtures.

Assay of cytokines in tissue culture supernatants describes a liquid suspension array for quantification of cytokines in tissue culture supernatants or serum. With this assay, it is possible to profile the level of multiple cytokines in a single well. The principle of this cytokine assay is similar to a capture sandwich immunoassay. Includes: Preparation for the Assay, Cytokine Assay, Reagents and Materials. - [Read Assay of Cytokines in Tissue Culture Supernatants]
The Bio-Plex cytokine assay employs a liquid suspension array for quantification of cytokines in tissue culture supernatants or serum. Using this 96-well microtiter plateformatted
assay, it is possible to profile the level of multiple cytokines in a single well. - [Read Assay of Cytokines in Tissue Culture Supernatants Protocol]
4 strains of E. coli are used in these studies: JM101 for M13 infection and isolation, XL1BMRF'for M13 or pUC-based DNA transformation, and ED8767 for cosmid DNA transformation. To maintain their respective F' episomes necessary for M13 viral infection, JM101 is streaked onto a M9 minimal media plate and XL1BMRF' is streaked onto an LB plate containing tetracycline. ED8767 is streaked onto an LB plate. These plates are incubated at 37degC overnight. For each strain, 3 ml. of appropriate liquid.. - [Read Bacterial Cell Maintenance Protocol]

Most manipulations with M13, including preparations of viral stocks and isolation of single- and double-stranded DNAs, begin with small-scale liquid cultures that are infected with an M13 plaque, picked from an agar plate. - [Read Growing Bacteriophage M13 in Liquid Culture Protocol]
There are essentially three parts to this protocol: 1. growth of at least 5x10e8 pfu phage to provide an inoculum growth of a larger liquid lysate that will produce about 5x10e12 pfu; 2. concentration and purification of the phage, and; 3. DNA preparation. - [Read Growth and Purification of 25-100 ug Lambda Clone DNA Protocol]
Protocol that isolates intact, high molecular weight DNA from yeast cells for subcloning and rare cutting restriction enzyme analysis. Using this protocol one can expect a yield of 100-200 µg of DNA per prep. - [Read High Molecular Weight Yeast Liquid DNA Preparation Protocol]
High-resolution SNP mapping by denaturing HPLC. A SNP mapping procedure that relies on resolving polymorphisms by denaturing HPLC without the necessity of determining the nature of the SNPs. They demonstrate the use of denaturing high-performance liquid chromatography to identify mutations in the candidate genes and to fine-map chromosomal breakpoints. - [Read High-resolution SNP mapping by denaturing HPLC]
Tubulin is polymerized into microtubules by incubating tubulin at 37°C with GTP. A nucleation seed is added when the purpose is to assay microtubule elongation. Tubulin can also be polymerized for the purposes of recycling the tubulin or labeling the microtubules with fluorescently labeled tubulin. Based on the protocol by Timothy Mitchison of Harvard University.
This Microarray Protocol Preparation of Fluorescent DNA Probes from Human mRNA protocol describes the production of probes labeled with the fluorescent dyes, Cy3 and Cy5, following the synthesis of cDNA from human mRNA and the hybridization of the probes to DNA microarrays.
Histone H1 Kinase Activity Assay Protocol. This protocol describes assaying kinase activity of a putative kinase using Histone H1 as the substrate. Histone H1 is the canonical kinase substrate in this type of assay. Phosphorylation of Histone H1 is assessed by SDS-Polyacrylamide gel electrophoresis followed by autoradiography.
This protocol describes the electroporation of the BMH 81-17 mut S strain that is recommended for tranformation of the site directed mutagenesis of dsDNA (See Protocol on Site-Directed Mutagenesis on Double Stranded DNA). BMH 81-17 mut S are a mismatch repair defective (mut S) Escherichia coli strain. The probability that the two mutations will cosegregate during the first round of DNA replication is increased in this strain.
