Proteins of the Cytoskeleton

 


Actin, Actin-Conjugates, Actin Binding Proteins...
Our quality is your guarantee. 


State of the art techniques rely on the use of actin conjugates to characterize actin dynamics or actin-ligand interactions.
Hypermol offers a variety of actin conjugates, from the frequently used skeletal muscle actin, to cardiac actin, smooth muscle actin and non-muscle actin. All available with several fluorescent or usefull biochemical modifications.

... and if the conjugate or protein your are looking is not available here, we are happy to give you a reasonable priced quotation that will surprise you. 


We exclusively manufacture the novel ATTO Actins, with superior properties compared to known conjugates for fluorescence microscopical techniques. They are suited for all types of lower resolution fluorescence microscopy, but especially for single molecule imaging (TIRF, STED, Storm etc.) or other high resolution imaging techniques.

Actin: a major protein of the cytoskeleton, a viral and bacterial invasion target

Actin filaments are not only one of the dynamic microfilament cellular structures that stabilize and organize the cytoskeleton. In its filamentous form actin is a major protein responsible for many phenomena of cell motility. Due to its various functions, the actin filament system is targeted by viruses (e.g., SARS CoV-2) and bacteria (e.g., Listeria).  It shown for example, that after binding of viruses to the cell, virus particles actively rearrange the actin cytoskeleton by regulating the FAK/Cofilin/Rac/Cdc42 pathway (Lv et al. 2019, J. Virol). While invasive bacteria like Shigella force their cell entry via the CDC42/Rac/Rho pathway, they also rearrange the actin cytoskeleton to build actin comet tails for fast spreading within the cell (Mounier et al., 1999. J. Cell Sci).

Actin-binding proteins interact in various ways with the plus- or minus ends (CapZ or gelsolin) of actin filaments either directly or associate laterally, like profilin, filamin or alpha-actinin. The ligand-actin interactions are targeted by intruders, drugs or natural compounds, leading to rearrangements of the cytoskeleton.


Cytoskeletal proteins of remarkable quality made for you by Hypermol

Choosing Hypermol as your supplier for actin and actin-binding proteins, you obtain your proteins as lyophilized powders, ready-to-use for many applications. Hypermol has developed a proprietary technique to gently lyophilize proteins while retaining the maximum biological activity. All proteins can be used for standard assays as supplied, but we recommend dialysis for highest accuracy in demanding assays.  

One of our top sellers is Pyrene-Actin, used for fluorometry or fluorimetry a sometimes referred. We manufacture 10% and 100% pyrenylated actin. While 10% Pyrene-Actin is used to measure actin polymerization and other actin dynamics, nucleation assays for instance are frequently with ≥ 20% Pyrene-Actin. This is obtained by mixing unlabelled Actin with Pyrene-Actin to the desired ratio. Using 100% Pyrene-Actin, an elegant technique is to mix it with e.g. non-muscle actin to obtain 5 or 10% pyrenylated actin, where 90-95% of the actin is non-muscle actin and the skeletal muscle becomes somehow negligible.   


Stability of actin and actin-binding proteins

Proteins are biologically active and most proteins of the cytoskeleton require sensitive handling. To preserve the activity, all protein solutions are kept at 0°C on ice. This holds especially true for G-actin, while F-actin is far longer stable on ice. Fluorescent actin and other fluorescent proteins are always kept in dark tubes and should only be exposed to light as long as necessary for handling. Hypermol manufactures fluorescent protein conjugates using the novel ATTO dyes.


Actin ATTO 488: fluorescent actin with full biological activity

You wish to work with fluorescent actin in microscopy or multiplexing assays? We offer e.g., ATTO 488-actin from various muscle sources – an excellent fluorescent actin conjugate – which can be combined with ATTO 565 and / or ATTO 647 actins.
