Analysis of Flow Cytometry Data Protocol - https://catalog.invitrogen.com/index.cfm?fuseaction=iProtocol.unitSectionTree&treeNodeID=9E661C2CE22FCCB1C294CD8376FD8830&objectid=6674E762AC837B13929440A1F32AAEF0

Category: Cell Biology and Cell Culture: Flow Cytometry Protocols: Flow Cytometry Data Analysis Protocols

Provides several approaches to flow cytometry data analysis. Frequency determinations based on analysis of single-parameter fluorescence histograms and dual-parameter contour plots are presented. Steps are described for calculating values for signal-to-noise ratios when logarithmic amplification is used for data collection. - [Read Analysis of Flow Cytometry Data Protocol]

Labeling Antibodies with Fluorochromes Protocol - http://www.cshprotocols.org/cgi/content/extract/2006/18/pdb.prot4285

Category: Antibody Protocols: Antibody Labeling Protocols

Direct labeling of purified antibodies is the method of choice when simultaneously visualizing two or more antibodies of the same species, class, or subclass. This allows the localization of multiple antigens to be compared in the same cell, tissue, or sample. Labeled primary antibodies are also useful for improving background-to-readout ratios, and they can be essential for immunoassays in which good quantification is needed. - [Read Labeling Antibodies with Fluorochromes Protocol]

Ligation Optimization Protocol - http://www.fhcrc.org/science/labs/fero/Protocols/Ligation.html

Category: Cloning Protocols

Protocol can be used to optimize ligation conditions for difficult to clone (e.g. very large) fragments. The principle is to independently characterize the ligation kinetics of the vector and insert DNA fragments and then to combine them in optimal ratios. - [Read Ligation Optimization Protocol]

Absorption Spectroscopy and Quantification of Filamentous Phage Protocol

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.
