Chicken IgY Antibodies
In many instances, raising antibodies in chicken has proven essential. Where genetically distant species is required e.g. conserved mammalian proteins, Genosphere Biotechnologies will produce your antibodies in chicken. IgY antibodies may be isolated from circulating blood of chicken or extracted and purified in high yields from egg yolks of immunized laying hens.
Anti-peptide service offer:
• Synthesis, purification & KLH conjugation of your peptide
• Immunization of 2 hens
• Eggs collection, yolk isolation or antiserum collection and IgY purification
√ ELISA titered IgY antibodies fraction
√ Pre-immune purified IgY
√ Full report with ELISA analysis data
• 2 mg of unconjugated peptide (with HPLC & MS data, purity >90%)
Anti-protein service offer (you provide the antigen):
• Immunization of 2 hens
• Eggs collection, yolk isolation or antiserum collection and IgY purification
√ ELISA titered IgY antibodies fraction
√ Pre-immune purified IgY
√ Full report with ELISA analysis data
Pre-immune eggs are collected and control IgYs are purified. Following four immunizations over a 70-days period, eggs or antiserum are collected and we isolate the IgY fraction (purity 90-95%). The final antibodies preparation is then titered by ELISA. In addition, the total IgY fraction may be further purified by affinity chromatography using a peptide- or antigen-column to yield a specific hen antibody. For large scale IgY production, multiple hen immunization, and timely supply over long periods, please contact us with your project details and we will design the most efficient strategy for you.

Probenart
Antigene (Proteine) können uns in Lösung, lyophilisiert, als Proteine im Gel, “inclusion bodies”, GST/His Fusionproteine, Proteinkonjugate, etc. zur Verfügung gestellt werden. Es muß jedoch beachtet werden, dass kleine Proteine (<10 kDa) und Peptide immer an ein Carrierprotein konjugiert werden müssen, um eine gute Immunantwort in den Tieren hervorrufen zu können. Antigene, die Substanzen wie Azid, Harnstoff, Imidazol oder Acrylamid enthalten, müssen als solche deutlich gekennzeichnet werden.
Anforderungen an die Proben (Antigene)
Für Proteinantigene über >10 kDa müssen 5 mg des Proteins zur Produktion von Antikörpern in Kaninchen und Hühnern zur Verfügung gestellt werden. Für die Herstellung von Antikörpern in Meerschweinchen und Ratten werden 2,5 mg benötigt, für die Immunisierung von Mäusen genügen 2 mg des Proteins (gelöst oder lyophilisiert). Eine minimale Konzentration der Proteinlösung von 1 mg/ml wird benötigt. Proteine in gepufferten NaCl Lösungen sind bevorzugt. Lösungen, die Harnstoff, Imidazol oder Natriumazid enthalten, müssen gegen eine NaCl-Lösung dialysiert werden.
Qualitätskontrolle
Die Immunantwort wird den gesamten Projektverlauf über kontrolliert und das Immunisierungs-programm wird, wenn dies notwendig ist entsprechend angepasst. Der abschließende ELISA wird für jedes der immunisierten Tiere einzeln an den Antiseren und den prä-Immunseren durchgeführt, die Ihnen zugesandt werden. Wir garantieren mindestens einen „good titer” für alle ihre Antiseren. Ein detailierter ELISA Report wird jedem ausgelieferten Projekt beigelegt.

Polyclonal egg yolk antibodies (IgY), which are often produced in chickens for research and diagnostic purposes, offer a non-invasive, high-yield alternative to traditional mammalian antibody production.
Source: These antibodies are derived from immunized hens and accumulate in the egg yolk.
Applications: They are used in immunology research, diagnostics, and, in some cases, passive immunization, such as targeting SARS-CoV-2.
Methodology: The antibodies can be isolated using techniques like PEG precipitation.
Advantages: They provide a robust alternative to mammalian antibodies (e.g., from rabbits) due to the non-invasive nature of egg collection.
Specific, high-affinity IgY antibodies have been developed for various applications, including targeting specific proteins and antigens.
IgY antibodies can be purified by affinity chromatography like IgG antibodies, too!
