RDI Divison of researchd Industries Intl  offers a wide line of  antibodies. Since no one antibody works best for all applications (neutralization, blotting, ELISA, etc), we offer many different types of antibodies to help solve this problem. Please inquire for other applications or types of antibodies not listed below.

ANTI-RNA POLYMERASE II   & related transciption antibodies

NOTE: The subclone of master clone ARNA3 is now available. As you may have been aware, the original cell line producing clone ARNA3 itself was destroyed last year but a subclone was able to be made from the same cell line. This new line is now available and we are accepting orders again for this product.



PRODUCT CODE         RDI-PRO65223    $375.00

                 replaces old cat#  RDI-CBL221 or cat#RDI-PRO61223

Background: Originally identified as the DNA-binding subunit of the general transcription factor TFIID, the TATA box-binding protein (TBP) is found in the cell complexed with several different sets of TBP associated proteins (TAFs). Several human general transcription factors including IIA, IIb, IID bind directly to TBP and modulate transcription initiation by RNA Polymerase II. In general, each TBP-TAF complex is dedicated to transcription by single RNA polymerase. transcription complexes such as SL1, TFIID and TFIIID are required for transcription by RNA polymerases I, II and III respectively.

isotype: mIgG1

package: 50ug or 150ug

antigen: full length human TBP protein

Use: Suitable for western blot on human and mouse   (other species not tested). Major band at Mw 37   kDa. Use RSV-3T3 as a positive control. Approx starting dilution 1:250.

Storage: Store at -20 DEG C upon receipt. Avoid frequent freeze thaw cycles. Recommend aliquoting. Avoid   frequent freeze thaw cycles.
