Goat anti human ige

Manufactured by Merck Group
Sourced in United Kingdom

Goat anti-human IgE is a laboratory reagent used to detect and quantify human immunoglobulin E (IgE) in biological samples. It is a polyclonal antibody produced by immunizing goats with human IgE. The antibody binds to human IgE, allowing for its identification and measurement in various immunoassay techniques.

Human mast cells were cultured from CD34+ progenitor cells and treated with human IgE (Chemicon International, Temecula, Calif) and goat anti-human IgE (1 μg/mL, Sigma) in the presence or absence of diclofenac (10 μmol/L), as described previously.37 (link) Supernatants of the cells were collected and measured for PGD2 and IL-13 with ELISA or stored at −80°C until used as mast cell supernatants for the treatment of ILC2s.

ELISA plates (Maxisorp, Nunc) were coated with 5 μg/mL of recombinant Phl p 7 (MRC/Asthma UK Protein Production Facility, King's College London, UK). Plates were blocked with PBS/1% BSA and washed throughout with PBS/0.05% Tween-20. 1 μg/mL purified 102.1F10 IgG4/IgE, negative isotype controls human myeloma IgG4 (Calbiochem), MOv18 IgE34 (link) and positive control Phl p 7 reactive patient serum12 (link) were incubated in triplicate for 2 hours at room temperature, followed by incubation with isotype specific antibodies. IgG4 antibodies were detected with mouse anti-human IgG4 biotin-conjugated antibody (clone G17-4, BD Biosciences), incubated at 1 μg/mL, followed by streptavidin–horseradish peroxidase (R&D Systems). IgE antibodies were detected with polyclonal goat anti-human IgE (Sigma-Aldrich) directly conjugated with horseradish peroxidase using the manufacturer's recommended dilutions. ELISA plates were developed using TMB (R&D Systems) by measuring absorbance at 450 nm.

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
