Product Specifications

Immunogen

This affinity purified ING4 Antibody was prepared from whole goat serum produced by repeated immunizations with a synthetic peptide corresponding to an internal region near aa 150-175 of Human ING4 protein (Inhibitor of growth family, member 4). This sequence only shows homology to isoform 1 for ING4. (Uniprot: Q9UNL4)

Reactivity Notes

Reactivity occurs against human p29 ING4 protein. The sequence is not present in isoforms 2 (see below). However, 100% homology is on record for this protein from human, dog, rat, and mouse. Cross reactivity with p29 ING4 protein from chimpanzee and chicken sources is also expected based on high homology (one amino acid change in sequence) by BLAST. Reactivity with p29 ING4 proteins from other sources is not known.

Description

This is an affinity purified antibody produced by immunoaffinity chromatography using the immunizing peptide after immobilization to a solid phase

Store vial at -20C prior to opening. Aliquot contents and freeze at -20C or below for extended storage. Avoid cycles of freezing and thawing. Centrifuge product if not completely clear after standing at room temperature. This product is stable for several weeks at 4C as an undiluted liquid. Dilute only prior to immediate use.

Scientific Data Images for ING4 Antibody

Western Blot: ING4 Antibody [NB100-1682]

Western Blot: ING4 Antibody [NB100-1682]

Western Blot: ING4 Antibody [NB100-1682] - Used at 1.0 ug/ml to detect ING4 (lane 2) present in a U2OS whole cell lysate over expressing the protein. A control lysate (lane 3) shows no background staining. Comparison to MW markers (lane 1) indicates detection of a single band at 29 kDa corresponding to ING4. A 4-20% TRIS-glycine gradient gel was used to separate the protein by SDS-PAGE under reducing conditions. The protein was transferred to nitrocellulose using standard methods. After blocking using 5% non-fat dry milk in PBS, the membrane was probed with the primary antibody overnight at 4 C followed by washes and reaction with a 1:20,000 dilution of IRDye800 conjugated Rb-a-Goat IgG [H&L] for 45 min at room temperature.
ING4 Antibody

ING4 Antibody

Anti-p29 ING4 polyclonal antibody detects ING4 protein by western blot in over expressed cell lysates. This antibody was used at 1.0 ug/ml to detect ING4 expression in control (-) and transformed U2OS and HeLa cell lysates. A predominant band corresponding to p29 ING4 is only seen in lysates from transformed cells. Personnel Communication, Motoko Unoki, NCI, NIH.

Background: ING4

p29 ING4 is a tumor suppressor protein similar to ING1 that may inhibit tumor progression by modulating the transcriptional output of signaling pathways which regulate cell proliferation. p29 ING4 has been shown to suppress brain tumor angio-genesis through transcriptional repression of RelA/ NFKB3 target genes when complexed with RelA. p29 ING4 may also specifically suppress loss of contact inhibition elicited by activated oncogenes such as MYC. p29 ING4 shows a nuclear localization and interacts with EP300, TP53, RelA, inhibits cell growth, and induces apoptosis. This protein contains a PHD-finger, which is a common motif in proteins involved in chromatin remodeling. Multiple alternatively spliced transcript variants have been observed. The accession number listed below is for variant (1) that encodes the longest isoform.
