Background of KAT3B/p300
E1A binding protein p300 also known as EP300 or p300 is a protein that in humans is encoded by the EP300 gene. The EP300 gene is located on the long (q) arm of the human chromosome 22 at position 13.2. This protein regulates the activity of many genes in tissues throughout the body. It plays an essential role in regulating cell growth and division, prompting cells to mature and assume specialized functions (differentiate), and preventing the growth of cancerous tumors. The EP300 protein appears to be critical for normal development before and after birth. It carries out its function by activating transcription. In addition, the protein functions as histone acetyltransferase that regulates transcription via chromatin remodeling, and is important in the processes of cell proliferation and differentiation. EP300 also mediates cAMP-gene regulation by binding specifically to phosphorylated CREB protein.

Figure 1. Western blot analysis of KAT3B/p300 using anti-KAT3B/p300 antibody (PB9178).
Electrophoresis was performed on a 5-20% SDS-PAGE gel at 70V (Stacking gel) / 90V (Resolving gel) for 2-3 hours.
lane 1: recombinant human kat3b/p300 protein 0.5ng.
After Electrophoresis, proteins were transferred to a Nitrocellulose membrane at 150mA 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-KAT3B/p300 antigen affinity purified polyclonal antibody (Catalog # PB9178) at 0.5 μg/mL overnight at 4°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 1:10000 for 1.5 hour at RT. The signal is developed using an Enhanced Chemiluminescent detection (ECL) kit (Catalog # EK1002) with Tanon 5200 system. A specific band was detected for KAT3B/p300 at approximately 50KD. The expected band size for KAT3B/p300 is at 50KD.

Question
Does anti-KAT3B/p300/EP300 antibody PB9178 work on goat WB with leukemic t-cell?
Verified Customer
Verified customer
Asked: 2019-10-09
Answer
Our lab technicians have not tested anti-KAT3B/p300/EP300 antibody PB9178 on goat. You can run a BLAST between goat and the immunogen sequence of anti-KAT3B/p300/EP300 antibody PB9178 to see if they may cross-react. If the sequence homology is close, then you can perform a pilot test. Keep in mind that since we have not validated goat samples, this use of the antibody is not covered by our guarantee. However we have an innovator award program that if you test this antibody and show it works in goat leukemic t-cell in WB, you can get your next antibody for free.
