Plant Tubulin Polymerization Assay
A robust assay for measuring the effects of compounds and proteins on dicotyledon tubulin polymerization. The kit contains soybean tubulin and sufficient reagents to perform 24 assays.

Gelsolin protein (human recombinant)
A new protein reagent with high purity and biological activity. Suitable for in vitro assays with or without other proteins or compounds, or as a tool to create short actin filaments.

Rac1 G-LISA™ Activation Assay
A new Rac activation assay that is specific for Rac1 only. No other commercially available pull-down or G-LISA™ assay is specifically able to detect just active Rac1.

Anti-Rac1 monoclonal antibody
Why risk your whole research project on antibodies that have not been fully tested for specificity. We recommend using QC Max™ antibodies from Cytoskeleton wherever possible. The new anti-Rac1 monoclonal antibody is specific for Rac1 over Rac2, Rac3, Cdc42 and Ras, in contrast to other commercial supplies which cross react to the other small G-proteins non-specifically.

Pre-formed Actin Filaments
Don't waste time preparing F-actin filaments for actin binding studies and myosin ATPase assays, use these pre-formed (lyophilized) filaments to accelerate your research. Highly quality controled to give within 8% batch to batch variability, ideal for drug discovery.

Cytoskelfix™ Advanced Cell Fixative
A new cell fixative for tissue culture cells, tissue samples and blood cells. Characterized by a vastly improved ability to retain both actin and tubulin structures and their associated proteins.

Cardiac Myosin
A new myosin to study cardiac myosin ATPase activity and to use in comparative drug discovery projects versus skeletal muscle myosin.

X-rhodamine Tubulin
A new fluorescent conjugate of active tubulin protein for cell microinjection and in vitro experiments.

Cell Permeable Rho Inhibitor
Specifically and efficiently inactivate RhoA, RhoB and RhoC in your cells in 2-4 h with this new product.  Works on a wide variety of cell types.

Rac G-LISA™ Activation Assay (ELISA format)
Measure Rac activity in your cells in less than 3 h with quantitative data and a large signal to noise ratio.  Works on a wide variety of cell and tissue types. Cat.# BK125.

Rap1a and Rap1b His tagged Proteins
Human Rap1a and Rap1b his tagged proteins for basic research and drug development.

Fungal pathogen Eg5 kinesin homolog
Purified Eg5-homolog motor domain of Aspergillus fumigatus for comparative basic research.

Smooth muscle actin
