Background of CTCFL

Anti-BORIS antibody is suitable for Cancer, Immunology and Nuclear Signaling research. BORIS (Brother of the Regulator of Imprinted Sites) also known as CCCTC-binding factor-like protein, is normally only expressed in the testis and expressed in a mutually exclusive manner with CTCF during male germ cell development. However, previous studies have shown that BORIS is abnormally activated in a wide range of human cancers. Expression of BORIS in normally BORIS-negative cells promotes cell growth that may lead to transformation. BORIS maps to the cancer-associated amplification region thought to contain an oncogene or dominant-immortalizing gene. BORIS is a candidate protein for the epigenetic reprogramming factor acting in the male germ line. BORIS is found in both the nucleus and cytoplasm. BORIS antibody can be used to investigate epigenetic regulation.

Antibody Validation

Boster validates all antibodies on WB, IHC, ICC, Immunofluorescence, and ELISA with known positive control and negative samples to ensure specificity and high affinity, including thorough antibody incubations.

Assay Dilutions Recommendation

The recommendations below provide a starting point for assay optimization. The actual working concentration varies and should be decided by the user.

ELISA: 1:2,000 - 1:10,000
WB: 1:200 - 1:2,000
BORIS affinity purified antibody has been tested for use in ELISA and by western blot.  Specific conditions for reactivity should be optimized by the end user. Expect a predominant band approximately 75 kDa in size corresponding to BORIS by western blotting in the appropriate cell lysate or extract.

Question

Does anti-BORIS antibody A04503 work on horse WB with testis?

Verified Customer

Verified customer

Asked: 2020-05-08

Answer

Our lab technicians have not validated anti-BORIS antibody A04503 on horse. You can run a BLAST between horse and the immunogen sequence of anti-BORIS antibody A04503 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 horse 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 horse testis in WB, you can get your next antibody for free.

Question

Would anti-BORIS antibody A04503 work for WB with testis?

A. Miller

Verified customer

Asked: 2020-04-24

Answer

According to the expression profile of testis, CTCFL is highly expressed in testis. So, it is likely that anti-BORIS antibody A04503 will work for WB with testis.

Question

I have a question about product A04503, anti-BORIS antibody. I was wondering if it would be possible to conjugate this antibody with biotin. I would need it to be without BSA or sodium azide. I am planning on using a buffer exchange of sodium azide with PBS only. Would there be problems for me to conjugate the antibody and store it in -20 degrees in small aliquots?

Verified Customer

Verified customer

Asked: 2020-01-16

Answer

We do not advise storing this antibody with PBS buffer only in -20 degrees. If you want to store it in -20 degrees it is best to add some cryoprotectant like glycerol. If you want carrier free A04503 anti-BORIS antibody, we can provide it to you in a special formula with trehalose and/or glycerol. These molecules will not interfere with conjugation chemistry and provide a good level of protection for the antibody from degradation. Please be sure to specify this in your purchase order.

Question

Will A04503 anti-BORIS antibody work on parafin embedded sections? If so, which fixation method do you recommend we use (PFA, paraformaldehyde, other)?

D. Parker

Verified customer

Asked: 2015-02-02

Answer

As indicated on the product datasheet, A04503 anti-BORIS antibody as been tested on WB. It is best to use PFA for fixation because it has better tissue penetration ability. PFA needs to be prepared fresh before use. Long term stored PFA turns into formalin, as the PFA molecules congregate and become formalin.
