FAQs

What does anti-rabbit antibody mean? ›

Anti-rabbit secondary antibodies are generated by immunizing a host animal with a pooled population of immunoglobulins (Ig) from the target species. In this case, the Ig would come from rabbits and be introduced into one of the available host species: goat, donkey, mouse, chicken, or sheep.

After the primary antibody is bound to the target protein, a complex with HRP-linked secondary antibody is formed. The LumiGLO^® is added and emits light during enzyme catalyzed decomposition.

Normal Rabbit IgG is an unconjugated rabbit polyclonal antibody that is routinely used as a non-specific IgG control in chromatin immunoprecipitation using our SimpleChIP^® Enzymatic Chromatin IP Kits #9002 and #9003.

The common rabbit IgG isotype has a molecular weight of 150 KD, with two heavy chains (about 50 KD each) and two light chains (about 25 KD each) under the non-reducing condition. Under the reducing condition, the molecular weights are 50 and 25 kD for heavy and light chain respectively.

For example, if someone with group B blood is given group A blood, their anti-A antibodies will attack the group A cells. This is why group A blood must never be given to someone who has group B blood and vice versa. As group O red blood cells do not have any A or B antigens, it can safely be given to any other group.

An anti-antibody means an antibody that will react as such with an immunoglobulin (Ig) molecule because that molecule is an antibody, not because that molecule is a γ-globulin. This does not imply that the antibody-combining site of that molecule is necessarily the locus of interaction.

Your doctor can test for IgG to figure out whether you've been infected by certain kinds of bacteria or viruses. Immunoglobulin M: Your body makes IgM antibodies when you are first infected with new bacteria or other germs. They are your body's first line of defense against infections.

Rabbits have long been used as a source of antibodies used as research tools. They can potentially generate antibodies targeting uncommon epitopes, including interesting epitopes that are less immunogenic in mice and humans.

Notably, rabbits only have one IgG isotype (one Cγ gene) compared to four IgG isotypes in mice (IgG1, IgG2a, IgG2b and IgG3) and humans (IgG1, IgG2, IgG3 and IgG4).

IgG has 4 different subclasses, IgG1— 4. IgG is always there to help prevent infections. It's also ready to multiply and attack when foreign substances get into the body. When you don't have enough, you are more likely to get infections.

Why are IgG antibodies important? ›

IgG antibodies are usually of higher affinity and are found in blood and in extracellular fluid, where they can neutralize toxins, viruses, and bacteria, opsonize them for phagocytosis, and activate the complement system.

Why Are Immunoglobulin Tests Done? Doctors may check immunoglobulin levels to see if a person has an infection or is protected from getting an infection (is immune to it). Doctors also use immunoglobulin tests to help diagnose immunodeficiencies (when the immune system isn't working as it should).

Positive: You produced the COVID-19 IgG antibody and have a high likelihood of prior infection. Some patients with past infections may not have experienced any symptoms. It is unclear at this time if a positive IgG infers immunity against future COVID-19 infection.

The IgG concentration of the rabbit serum was 7.66 mg/mL (±3%), which is consistent with that reported (5–10 mg/mL) by a previous study [22].

The Anti-Rabbit IgG (H+L), HRP Conjugate, antibody binds to both heavy and light chains for all rabbit IgG subclasses. As with all antibodies, in certain applications some species-dependent antigen-dependent cross-reactivity may be observed. The product (unless otherwise noted)is supplied as a 1mg/ml solution.

The anti-double stranded DNA (anti-dsDNA) tests are used to help diagnose and monitor lupus, also called systemic lupus erythematosus or SLE, a chronic inflammatory autoimmune disorder in which the immune system mistakenly targets the body's own cells and tissues.

Rabbit recombinant monoclonal antibodies are identical immunoglobulins directed against a specific epitope. These antibodies provide a consistent alternative to polyclonal antibodies and traditional hybridoma monoclonals, with the added benefit of an in vitro development option.

Human anti-mouse antibodies (HAMA) are human immunoglobulins with specificity for mouse immunoglobulins. This topic currently is of interest because of the increased use of monoclonal mouse antibodies as diagnostic reagents both for in vitro laboratory measurements and for in vivo imaging studies.
