Description

Mouse Monoclonal Antibody

Description: The V9 monoclonal antibody recognizes human Vimentin, a 57 kDa protein that functions as a structural component of intermediate filaments. Vimentin is expressed in cells derived from the mesenchyme but also in specific populations such as radial glia and immature glial cells, pancreatic precursor cells. It is proposed to be a marker of cardiac differentiation. In neural cells, vimentin expression is gradually replaced by neurofilaments. Reports have also shown surface expression of vimentin on activated macrophages, platelets, as well as apoptotic T cells and neutrophils. This antibody also recognizes canine (dog), rat and chicken vimentin but does not recognize mouse vimentin. Applications Reported: This V9 antibody has been reported for use in immunohistochemical staining of frozen tissue sections, immunohistochemical staining of formalin-fixed paraffin embedded tissue sections, and immunocytochemistry. Applications Tested: This V9 antibody has been tested by immunocytochemistry of fixed and permeabilized cells and can be used at less than or equal to 5 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 ...

Vimentin is a developmentally regulated intermediate filament protein (IFP) found in cells of mesenchymal origin. It is believed to be involved with the intracellular transport of proteins between the nucleus and plasma membrane. Unlike other IFP proteins, vimentin is expressed, along with desmin, during the early stages of cellular development. During the development process, vimentin is exchanged for new, tissue-specific IFPs. Vimentin has been implicated to be involved in the rate of steroid synthesis via its role as a storage network for steroidogenic cholesterol containing lipid droplets. Vimentin phosphorylation by a protein kinase causes the breakdown of intermediate filaments and activation of an ATP and myosin light chain dependent contractile event. This results in cytoskeletal changes that facilitate the interaction of the lipid droplets within mitochondria, and subsequent transport of cholesterol to the organelles leading to an increase in steroid synthesis.

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.

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.
