Oligoclonal Antibodies—Exceptional Consistency Helps Save Time and Money
Invitrogen's oligoclonal antibodies are a pool of monoclonal rabbit IgG antibodies targeted against a specific antigen. Oligoclonal antibodies are produced by transfection of mammalian cells with heavy and light chain antibody cDNAs. This provides you with the highest consistency between lots, eliminating the need to revalidate your assays for each lot.
Oligoclonal Antibody Advantages Include:
- Superior lot-to-lot consistency
- Extremely high specificity and sensitivity
- Validation by Invitrogen
Specific for NFκB p65
NF-κB p65 (nuclear factor kappa-light-chain-enhancer of activated B cells Transcription Factor p65), also known as RELA, belongs to the Rel protein family. NF-κB molecules exist in the cytoplasm of most cells in an inert, non-DNA-binding form. Some NF-κB homo- and heterodimers are retained in the cytosol by the inhibitory molecules IκBα, IκBβ, and IκBε. Apparently ankyrin repeats (which mediate protein-protein interactions) in the C-terminal regions of p105 and p100 fold back to mask the nuclear localization sequence of p65 (Ref 1). Activation of NF-κB occurs predominantly through the phosphorylation and degradation of IκB proteins (Ref 2-4). Free NF-κB, which translocates to the nucleus, upregulates expression of many genes involved in developmental processes, cellular growth, apoptosis, and immune and inflammatory responses (Ref 5).
Obtain More Reliable Data
The proprietary recombinant technology employed in the production of Invitrogen’s oligoclonal antibodies means you are assured of the greatest degree of reliability. Staining of nonspecific proteins is virtually eliminated while very high sensitivity is achieved
Detect Low Levels of Target Protein
Invitrogen's oligoclonal antibodies demonstrate much higher sensitivity than ordinary antibodies. Proteins expressed in low levels can be detected with high specificity allowing you to use less of your precious samples than with ordinary antibodies.
Recombinant Rabbit IgG—Use Like Any Other IgG Antibody
As with traditional IgG antibodies, gel electrophoresis of rabbit oligoclonal antibodies produces a 150 kDa band under non-reducing conditions and 50 kDa and 25 kDa bands under reducing conditions.
