Description

Mouse Monoclonal Antibody

Description: This MF20 monoclonal antibody recognizes the heavy chain of myosin II, specificially the light meromyosin portion, in cardiac and skeletal muscle of vertebrates. Myosin II is composed of two heavy chains and four light chains. The 220-kDa myosin heavy chain exists as four different isoforms due to alternative splicing. Myosins interact with actin and hydrolyze ATP to function in muscle contraction, cytokinesis, and phagocytosis. The MF20 has been shown to react to myosin from a variety of mammalian, avian and amphibian species, including rat, mouse, human, chicken, zebrafish, and dog. Applications Reported: This MF20 antibody has been reported for use in immunohistochemical staining, immunocytochemistry, and immunohistochemical staining of frozen tissue sections. Applications Tested: This MF20 antibody has been tested immunocytochemistry on fixed and permeabilized C2C12 cells at less than or equal to 10 μg/mL. It is recommended that the antibody be carefully titrated for optimal performance in the assay of interest. eFluor™ 660 is a replacement for Alexa Fluor™ 647. eFluor™ 660 emits at 659 nm and is excited with the red laser (633 nm). Please make sure that your instrument is capable of detecting this fluorochome. Excitation: 633-647 nm; Emission: 668 nm; Laser: Red Laser. Filtration: 0.2 μm post-manufacturing filtered.

Target protein includes a fast myosin isoform expressed in skeletal muscle and has function involved in Muscle contraction.

Frequently Asked Questions (FAQs)

I am unable to analyze my cells stained with eFluor Organic Dyes today. What options do I have?

Our options will depend on the samples you are analyzing.

If cell viability is not critical, you can store your stained samples at 4 degrees C or on ice overnight in the dark and analyze the following day.

For samples stained with eFluor organic fluorochromes, we recommend that cells be suspended in 100 uL of Flow Cytometry Staining Buffer (Cat. No. 00-4222) and 100 uL of eBioscience IC Fixation Buffer (Cat. No. 00-8222); samples can be incubated for up to 3 days at 4 degrees C in the dark. Alternatively, the 1-step Fix/Lyse Solution (Cat. No. 00-5333) can be used. This is a great option when working with whole blood but also works for other cell types.

Can the eFluor Organic fluorochromes be used for intracellular staining?

Yes, the eFluor Organic fluorochromes can be used for intracellular staining. The eFluor organic fluorochromes maintain bright signal and require minimal changes in compensation when fixed with eBioscience IC Fixation Buffer (Cat. No. 00-8222-49) and Permeabilization Buffer (Cat. No. 00-8333-56) or 1-step Fix/Lyse Solution (Cat. No. 00-5333-54, 00-5333-57) (as compared to live cells).

Is the eFluor 660 fluorochrome compatible with Anti-Cy5/Alexa Fluor 647 beads?

Yes, in-house studies have demonstrated that the eFluor 660 fluorochrome is recognized by Anti-Cy5/Alexa Fluor 647 beads. Side by side studies with Alexa Fluor 647 versus eFluor 660 conjugated antibodies have demonstrated comparable results.

What buffers are compatible with the eFluor Organic fluorochromes and eVolve QDots?

The eFluor Organic fluorochromes and eVolve QDots can be used with flow staining buffers containing PBS and protein.

What is the difference between eFluor Organic Dyes and eVolve Qdots?

The eFluor Organic Dyes (eFluor 450, APC-eFluor 780, PerCP-eFluor 710, eFluor 710) are conventional fluorochromes. In contrast, the eVolve line of products are Quantum dots.

Are the eFluor Organic Dyes photo-labile?

As with other fluorochromes, we recommend minimal exposure to light to maintain optimal signal.
