Product description

Secondary antibody conjugated to Alexa Fluor 488 with high specificity and low cross-reactivity for rabbit IgG detection.

The Invitrogen Donkey anti-Rabbit IgG (H+L) Highly Cross-Adsorbed Secondary Antibody, Alexa Fluor™ 488 is a meticulously engineered secondary antibody designed to detect rabbit immunoglobulins with exceptional specificity and minimal cross-reactivity. This antibody is conjugated to Alexa Fluor™ 488, a bright green-fluorescent dye, making it ideal for various fluorescence-based applications.

Key features:

  • Highly cross-adsorbed: Affinity-purified to reduce cross-reactivity with proteins from multiple species, including bovine, chicken, goat, guinea pig, hamster, horse, human, mouse, rat, and sheep.
  • Bright fluorescence: Conjugated to Alexa Fluor™ 488, providing a strong, green fluorescence signal suitable for various imaging techniques.
  • Versatile applications: Optimised for use in immunocytochemistry (ICC), immunohistochemistry (IHC), and flow cytometry, facilitating diverse experimental protocols.
  • High sensitivity: Enhanced signal detection allows for the identification of low-abundance targets, crucial in detailed cellular analyses.

Applications:

  • Cellular imaging: Widely used in immunofluorescence microscopy to visualise protein localisation within cells.
  • Tissue analysis: Employed in immunohistochemical staining to detect specific antigens in tissue sections.
  • Flow cytometry: Facilitates the detection and quantification of rabbit IgG-bound antigens in cell populations.

Relevance to biotechnology:

This secondary antibody is indispensable in biotechnology research, particularly in molecular biology, cell biology, and biomedical engineering. Its high specificity and sensitivity make it a valuable tool in protein expression studies, signal transduction research, and diagnostic assay development.

Commonly used in:

  • University laboratories: For academic research and teaching purposes.
  • Biotechnology companies: Involved in product development and quality control.
  • Clinical research facilities: Conducting diagnostic and therapeutic studies.

First released prior to 2010, this antibody remains a staple in scientific research due to its reliability and performance.

Why Questpair exists

Lab equipment markets are fragmented. Buyers spend weeks calling distributors, comparing quotes, and verifying supplier reliability. Sellers struggle to reach global research labs.

We built Questpair to fix this. Every supplier on the platform is verified before listing. Every quote you receive comes from a real, vetted seller. AI prepares your case in minutes, then a real specialist takes over.

We're an independent team based in The Netherlands, working with research labs and procurement teams across Europe and worldwide.

Frequently asked questions

How long does laboratory equipment typically last?

With a service contract, ten to fifteen years is normal for most benchtop instruments. Detectors and pumps are the parts that wear first.

Can I get service for older equipment?

Often, yes. Verified suppliers frequently work with service partners converting the instrument. If applicable, we can list servicing options alongside the offer.

Where can I buy parts?

Ask a scientist through the request button. Parts are often available even when the instrument itself is discontinued.

What is the typical lead time for refurbished equipment?

Two to six weeks, depending on refurbishment scope and whether calibration is included.

Does laboratory equipment ship internationally?

We ship to 38 countries. Crating and customs handling are quoted with the instrument.
