Description

Rat Isotype Control

Description: The monoclonal rat IgG1, kappa is useful as an isotype control immunoglobulin. Applications Reported: This eBRG1 antibody has been reported for use in immunohistochemical and immunocytochemical staining. Applications Tested: This eBRG1 antibody has been tested by immunohistochemistry on frozen mouse tissue. Use isotype control at the same concentration as experimental antibody. Filter Recommendation: When using this eFluor® 570 antibody conjugate, we recommend a filter that will capture the 570 emission wavelength (for example, Excitation 545/25, 565LP, Emission 605/70). A standard Alexa Fluor® 555 or TRITC filter is acceptable. Excitation: 555 nm; Emission: 570 nm

Rat IgG1 is a subclass of immunoglobulin G (IgG) antibodies that are commonly used in research and diagnostics. These antibodies are produced by rats in response to an antigen and can be purified from serum or hybridoma cell culture supernatants. Rat IgG1 is often used as a negative control in experiments, as it does not bind to many mammalian antigens. It is also used in immunohistochemistry, flow cytometry, and western blotting to detect specific antigens. Gene targeting is a powerful tool used to manipulate the rat genome and generate animal models for studying human diseases. With gene targeting, specific genes can be knocked out, inserted, or modified to investigate their role in disease pathogenesis.

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).

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.
