Why is the actual band size different from the predicted Western blotting is a technique that separates proteins based on size - in general, the smaller the protein the faster it migrates through the gel. However, migration is also affected by other factors and so the actual band size observed may differ from that predicted. Common factors include... · post-translational modification - e.g. phosphorylation, glycosylation etc which increases the size of the protein · post-translation cleavage - e.g. many proteins are synthesized as pro-proteins, and then cleaved to give the active form, e.g. pro-caspases · splice variants - alternative splicing may create different sized proteins from the same gene · relative charge - the composition of amino acids (charged vs non-charged) multimers - e.g. dimerisation of a protein. This is usually prevented in reducing conditions, although strong interactions can result in the appearance of higher bands.)

NCBI and Uniprot Product Information
NCBI Description
This gene encodes a member of the prefoldin alpha subunit family. The encoded protein is one of six subunits of prefoldin, a molecular chaperone complex that binds and stabilizes newly synthesized polypeptides, thereby allowing them to fold correctly. The complex, consisting of two alpha and four beta subunits, forms a double beta barrel assembly with six protruding coiled-coils. The encoded protein may also repress the transcriptional activity of the proto-oncogene c-Myc. Alternatively spliced transcript variants encoding different isoforms have been described.

Uniprot Description
PFDN5: Binds specifically to cytosolic chaperonin (c-CPN) and transfers target proteins to it. Binds to nascent polypeptide chain and promotes folding in an environment in which there are many competing pathways for nonnative proteins. Represses the transcriptional activity of MYC. Belongs to the prefoldin subunit alpha family. 3 isoforms of the human protein are produced by alternative splicing.
Protein type: Transcription, coactivator/corepressor
Chromosomal Location of Human Ortholog: 12q12
Cellular Component: cytoplasm; nucleus; prefoldin complex
Molecular Function: protein binding; transcription corepressor activity; unfolded protein binding
Biological Process: 'de novo' posttranslational protein folding; cellular protein metabolic process; negative regulation of transcription, DNA-dependent; protein folding; regulation of transcription, DNA-dependent; retina development in camera-type eye

Product Notes
The PFDN5 pfdn5 (Catalog #AAA715290) is an Antibody produced from Rabbit and is intended for research purposes only. The product is available for immediate purchase. The Rabbit anti-human Prefoldin subunit 5 polyclonal Antibody, Biotin conjugated reacts with Human and may cross-react with other species as described in the data sheet. AAA Biotech's Prefoldin subunit 5 can be used in a range of immunoassay formats including, but not limited to, ELISA (EIA). Researchers should empirically determine the suitability of the PFDN5 pfdn5 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 "Prefoldin subunit 5, 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
