p130 antibody

Catalog No. ABIN349607

Product Details anti-p130 Antibody

Target: p130 (RBL2) (Retinoblastoma-Like 2 (p130) (RBL2))

Reactivity: Human, Chimpanzee

Host: Rabbit

Clonality: Polyclonal

Conjugate: This p130 antibody is un-conjugated

Application: ELISA, Western Blotting (WB)

Specificity: This antiserum is directed against Spa310 and reacts with the Spa3120 domain of pRb2/p130 from human tissues.  Based on the sequence we expect this antibody to react as well Spa310 from chimpanzee and orangutan, and with lesser affinity, Spa310 from horse, dog, bovine, rat and opossum.

Cross-Reactivity: Chimpanzee

Characteristics: Spa310 is a 39 aa-long polypeptide encoded by a sequence which resides in the spacer region of the tumor suppressor Rb2 gene. Rb2 is a member of the retinoblastoma (Rb) gene family. Proteins in this family, which also include pRb/p105 and pRb/p107, are important cellular factors which play well-recognized roles as tumor and growth suppressors. Both p107 and pRb2/p130 share the ability to physically interact and inhibit the kinase activity of the Cdk2/Cyclin A and Cdk2/Cyclin E complexes, which play critical roles in cell cycle regulation. Spa310 is the region of the pRb2/p130 protein that is responsible for Cdk2/Cyclin E/A inhibition. Spa310 has also been shown to suppress cell growth as observed by colony formation, and to reduce volume of tumor growth in nude mice, likely through arrest in the G 0 /G 1 phase of the cell cycle. Understandably, the Spa310 small molecule represents a potentially significant pharmaceutical product in the treatment of hyperproliferative disorders.

Purification: affinity purified

Sterility: Sterile filtered

Immunogen: This affinity purified antibody was prepared by repeated immunizations with a synthetic peptide corresponding to the Spa310 sequence of pRb2/p130 protein.  A residue of cysteine was added to facilitate coupling.
Immunogen Type: Peptide

Isotype: IgG

Application Details

Application Notes: This affinity purified antibody is suitable for ELISA and western blotting.  Specific conditions for reactivity should be optimized by the end user.  Expect a band approximately 130 kDa in size corresponding to pRb2/p130, and a band approximately 4.2kDa in size corresponding to Spa310 peptide (latter not shown), by western blotting in the appropriate cell lysate or extract.
