Rabbit anti-Human Topoisomerase III Beta Polyclonal Antibody | anti-TOP3b antibody
Polyclonal Antibody to Topoisomerase III Beta (TOP3b)
Immunohistochemistry: 5-20ug/mL
Immunocytochemistry: 5-20ug/mL
Optimal working dilutions must be determined by end user.
Avoid repeated freeze/thaw cycles.
Store at 4 degree C for frequent use.
Aliquot and store at -20 degree C for 24 months.
Stability Test:
The thermal stability is described by the loss rate. The loss rate was determined by accelerated thermal degradation test, that is, incubate the protein at 37 degree C for 8h, and no obvious degradation and precipitation were observed. The loss rate is less than 5% within the expiration date under appropriate storage condition.
NCBI and Uniprot Product Information
NCBI Description
This gene encodes a DNA topoisomerase, an enzyme that controls and alters the topologic states of DNA during transcription. This enzyme catalyzes the transient breaking and rejoining of a single strand of DNA which allows the strands to pass through one another, thus relaxing the supercoils and altering the topology of DNA. The enzyme interacts with DNA helicase SGS1 and plays a role in DNA recombination, cellular aging and maintenance of genome stability. Low expression of this gene may be related to higher survival rates in breast cancer patients. This gene has a pseudogene on chromosome 22. Alternate splicing results in multiple transcript variants. Additional alternatively spliced transcript variants of this gene have been described, but their full-length nature is not known. [provided by RefSeq, Aug 2013]
Uniprot Description
TOP3B: Releases the supercoiling and torsional tension of DNA introduced during the DNA replication and transcription by transiently cleaving and rejoining one strand of the DNA duplex. Introduces a single-strand break via transesterification at a target site in duplex DNA. The scissile phosphodiester is attacked by the catalytic tyrosine of the enzyme, resulting in the formation of a DNA-(5'-phosphotyrosyl)-enzyme intermediate and the expulsion of a 3'-OH DNA strand. The free DNA strand than undergoes passage around the unbroken strand thus removing DNA supercoils. Finally, in the religation step, the DNA 3'-OH attacks the covalent intermediate to expel the active-site tyrosine and restore the DNA phosphodiester backbone. Possesses negatively supercoiled DNA relaxing activity. Belongs to the type IA topoisomerase family. 3 isoforms of the human protein are produced by alternative splicing.

The Polyclonal Antibody to Topoisomerase III Beta (TOP3b) reacts with Human and may cross-react with other species as described in the data sheet. AAA Biotech's Topoisomerase III Beta can be used in a range of immunoassay formats including, but not limited to, Western Blot (WB), Immunocytochemistry (ICC), Immunohistochemistry (IHC) Formalin/Paraffin, Immunoprecipitation (IP). Western blotting: 0.5-2ug/mL Immunohistochemistry: 5-20ug/mL Immunocytochemistry: 5-20ug/mL Optimal working dilutions must be determined by end user. Researchers should empirically determine the suitability of the TOP3b top3b for an application not listed in the data sheet. Researchers commonly develop new applications and it is an integral, important part of the investigative research process. It is sometimes possible for the material contained within the vial of "Topoisomerase III Beta, Polyclonal Antibody" to become dispersed throughout the inside of the vial, particularly around the seal of said vial, during shipment and storage. We always suggest centrifuging these vials to consolidate all of the liquid away from the lid and to the bottom of the vial prior to opening. Please be advised that certain products may require dry ice for shipping and that, if this is the case, an additional dry ice fee may also be required.Precautions
