Description

Rat Isotype Control

Description: The monoclonal rat IgG2a is useful as an isotype control immunoglobulin. Applications Reported: Rat IgG2a Isotype Control eFluor® 615 has been reported for use in immunohistochemical and immunocytochemical staining. Applications Tested: Rat IgG2a Isotype Control eFluor® 615 has been tested by immunocytochemistry or immunohistochemistry. Use at the same concentration as the experimental antibody. This product has not been validated for flow cytometric analysis. Filter Recommendation: When using this eFluor® 615 antibody conjugate, we recommend a filter that will capture the 615 emission wavelength (for example, Excitation 560/55, 585LP, Emission 645/75). A standard Alexa Fluor® 594 filter is acceptable. Excitation: 595 nm; Emission: 615 nm. Filtration: 0.2 μm post-manufacturing filtered.

Rat IgG2a is an immunoglobulin subclass that is commonly used in research and diagnostic applications. It is produced by the rat immune system and is known for its ability to activate complement and mediate antibody-dependent cell-mediated cytotoxicity (ADCC). Rat IgG2a has a molecular weight of approximately 160 kDa and is composed of two heavy chains and two light chains. It is often used as a control or reference antibody in experiments involving rat models, and is also commonly used in flow cytometry and immunohistochemistry applications.

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.

Are the eFluor Organic Dyes photo-labile?

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