Description

Rat Isotype Control

Description: The monoclonal rat IgM K is useful as an isotype control immunoglobulin. Applications Reported: Rat IgM Isotype Control eFluor® 660 has been reported for use in flow cytometric analysis. Applications Tested: Rat IgM Isotype Control has been tested by flow cytometric analysis of normal human peripheral blood cells and mouse spleen cells. It should be used at the same concentration as the experimental antibody. 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.

Rat IgM is an immunoglobulin M isotype antibody produced by B cells in rats. It plays a crucial role in the immune system by recognizing and neutralizing antigens, such as bacteria and viruses. Rat IgM has been extensively studied and is widely used in research applications, including immunology, microbiology, and biotechnology. It is commonly used as a control in experiments, as well as a diagnostic tool for detecting infectious diseases and autoimmune disorders. Researchers have developed various techniques for producing and purifying Rat IgM, including hybridoma technology, protein A/G chromatography, and affinity chromatography. Rat IgM is a valuable tool in the field of immunology, and its use has contributed to a better understanding of the immune system and the development of new treatments for various diseases.

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 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.
