Background of COMP/Thrombospondin-5

COMP is a pentameric extracellular matrix protein that catalyzes the assembly of collagens and promotes formation of well-defined fibrils. This gene is mapped to 19q13.32. The protein encoded by this gene is a cytoplasmic enzyme involved in energy homeostasis and is an important serum marker for myocardial infarction. The encoded protein reversibly catalyzes the transfer of phosphate between ATP and various phosphogens such as creatine phosphate. It acts as a homodimer in striated muscle as well as in other tissues, and as a heterodimer with a similar brain isozyme in heart. The encoded protein is a member of the ATP:guanido phosphotransferase protein family.

Antibody Validation

Question

We have tried in the past anti-COMP antibody for WB on tendon of biceps brachii last year. I am using mouse, and We want to use the antibody for ICC next. We are interested in examining tendon of biceps brachii as well as cartilage in our next experiment. Could give a recommendation on which antibody would work the best for ICC?

Verified Customer

Verified customer

Asked: 2019-12-03

Answer

I took a look at the website and datasheets of our anti-COMP antibody and I see that A02443-1 has been validated on mouse in both WB and ICC. Thus A02443-1 should work for your application. Our Boster satisfaction guarantee will cover this product for ICC in mouse even if the specific tissue type has not been validated. We do have a comprehensive range of products for ICC detection and you can check out our website bosterbio.com to find out more information about them.

Question

Does A02443-1 anti-COMP antibody work on parafin embedded sections? If so, which fixation method do you recommend we use (PFA, paraformaldehyde, other)?

Verified Customer

Verified customer

Asked: 2019-11-26

Answer

It shows on the product datasheet, A02443-1 anti-COMP antibody as been validated on IF. 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.

Question

My question regarding product A02443-1, anti-COMP 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?

A. Huang

Verified customer

Asked: 2013-06-20

Answer

We do not recommend 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 A02443-1 anti-COMP 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.
