Western Blot (WB) of anti-TAF8 antibody

Figure 1. Western blot analysis of TAF8/TBN using anti-TAF8/TBN antibody (MBS1755780).

Electrophoresis was performed on a 5-20% SDS-PAGE gel at 70V (Stacking gel)/90V (Resolving gel) for 2-3 hours. The sample well of each lane was loaded with 30 ug of sample under reducing conditions.

Lane 1: human Hela whole cell lysates,
Lane 2: human THP-1 whole cell lysates,
Lane 3: rat heart tissue lysates,
Lane 4: rat testis tissue lysates,
Lane 5: rat PC-12 whole cell lysates,
Lane 6: mouse heart tissue lysates,
Lane 7: mouse testis tissue lysates,
Lane 8: mouse lung tissue lysates,
Lane 9: mouse RAW264.7 whole cell lysates.

After electrophoresis, proteins were transferred to a nitrocellulose membrane at 150 mA for 50-90 minutes. Blocked the membrane with 5% non-fat milk/TBS for 1.5 hour at RT. The membrane was incubated with rabbit anti-TAF8/TBN antigen affinity purified polyclonal antibody (#MBS1755780) at 0.5 ug/mL overnight at 4 degree C, then washed with TBS-0.1%Tween 3 times with 5 minutes each and probed with a goat anti-rabbit IgG-HRP secondary antibody at a dilution of 1:5000 for 1.5 hour at RT. The signal is developed using an Enhanced Chemiluminescent detection (ECL) kit with Tanon 5200 system. A specific band was detected for TAF8/TBN at approximately 34 kDa. The expected band size for TAF8/TBN is at 34 kDa.

Immunofluorescence (IF) of anti-TAF8 antibody

Figure 2. IF analysis of TAF8/TBN using anti-TAF8/TBN antibody (MBS1755780).

TAF8/TBN was detected in an immunocytochemical section of Caco-2 cells. Enzyme antigen retrieval was performed using IHC enzyme antigen retrieval reagent (AR0022) for 15 mins. The cells were blocked with 10% goat serum. And then incubated with 5 ug/mL rabbit anti-TAF8/TBN Antibody (MBS1755780) overnight at 4 degree C. DyLight488 Conjugated Goat Anti-Rabbit IgG (MBS177405) was used as secondary antibody at 1:100 dilution and incubated for 30 minutes at 37 degree C. The section was counterstained with DAPI. Visualize using a fluorescence microscope and filter sets appropriate for the label used.

NCBI Summary for TAF8

This gene encodes one of several TATA-binding protein (TBP)-associated factors (TAFs), which are integral subunits of the general transcription factor complex TFIID. TFIID recognizes the core promoter of many genes and nucleates the assembly of a transcription preinitiation complex containing RNA polymerase II and other initiation factors. The protein encoded by this gene contains an H4-like histone fold domain, and interacts with several subunits of TFIID including TBP and the histone-fold protein TAF10. Alternatively spliced transcript variants have been described, but their biological validity has not been determined. [provided by RefSeq, Jul 2008]

UniProt Comments for TAF8

TBN: Transcription factor TFIID is one of the general factors required for accurate and regulated initiation by RNA polymerase II. Mediates both basal and activator-dependent transcription. Plays a role in the differentiation of preadipocyte fibroblasts to adipocytes, however, does not seem to play a role in differentiation of myoblasts. Required for the integration of TAF10 in the TAF complex. May be important for survival of cells of the inner cell mass which constitute the pluripotent cell population of the early embryo. Belongs to the TAF8 family. 3 isoforms of the human protein are produced by alternative splicing.

Chromosomal Location of Human Ortholog: 6p21.1

Cellular Component: nucleoplasm; nucleus; perinuclear region of cytoplasm; transcription factor TFIID complex

Molecular Function: protein binding

Biological Process: maintenance of protein localization in nucleus; positive regulation of transcription, DNA-dependent; regulation of fat cell differentiation; snRNA transcription from RNA polymerase II promoter
