  • Product overview

    F-actin Staining Kit - Red Fluorescence | Cytopainter (ab112127) fluorescence imaging kits are a set of fluorescence imaging tools for labeling sub-cellular organelles such as lysosomes, mitochondria, and actin filaments. The selective staining of cell compartments provides a powerful method for studying cellular events in a spatial and temporal context.

    ab112127 is designed to stain F-actins in fixed cells with red fluorescence. The red fluorescent phalloidin conjugate, which is selectively bound to F-actins, is a high-affinity probe for F-actins. The red fluorescent phalloidin conjugate has Ex/Em = 594/610 nm. Used at nanomolar concentrations, phallotoxins can be conveniently used to label, identify and quantitate F-actins in formaldehyde-fixed and permeabilized tissue sections, cell cultures or cell-free experiments. The red fluorescent phalloidin conjugate has good thermal and photo stability.

    ab112127 provides all the essential components with an optimized labeling protocol. It is an excellent tool for preserving fluorescent images of particular cells, and can also be used for fluorescence microscope demonstrations.

CytoPainter F-actin Staining Kit for IHC-P

Poor Excellent 5/5 (Ease of Use)
I have tried this Kit on paraffin embedded sections of adult human kidney. Because the protocol is for ICC I adjusted it to IHC. In addition, I combined it with HLA staining (ab52922, routinely used at our lab) to visualize the tissue.

Deparaffinization and antigen retrieval was done with commercial - ZYTOMED's OmniPrep (pH 9). Slides were washed with PBS-Tween (0.05%) and blocked (commercial - Invitrogen's CAS-Block) – 1h at RT. Anti-HLA was incubated for 1h at RT and washed with PBST three times.

Phalloidin reagent was prepared according to protocol in three dilutions: 1/250, 1/500 and 1/1000. Secondary Alexa flour 488 donkey anti rabbit was added to each reagent tube at a 1/1200 dilution. Slides were incubated for 1h at RT and then washed three times with PBST. Secondary only slices (only Secondary Alexa flour 488) were used to determine exposure time threshold.
There was no signal above background in all three Phalloidin dilutions. The picture (at the Texas Red Tfilter) was taken in slight overexposure to show the absent of staining.

Cytopainter F-actin in Hydractinia

Excellent Excellent 5/5 (Ease of Use)
We used cytopainter F-actin staining kit to study morphology in the model organism Hydractinia during head regeneration. We fixed our whole animals in 4% pararfomaldehde in PBS followed by three ten minute washes in 0.1%triton in PBS. The animals were incubated in component in at a 1:500 dilution in component B for 45 minutes. They were then washed in PBS three times and mounted in fluorescent mounting medium.
The picture shows F-actin staining(Red) and Hoescht nuclear staining(blue). The image was taken on a spinning disc confocal microscope.
