  • 产品描述:

    The Mouse tartrate-resistant acid phosphatase 5b (TRACP-5b) ELISA Kit is designed to measure TRACP-5 in biological samples, including serum, plasma, and tissue homogenates, in a quantitative fashion. This kit has been verified by multiple tests with advantages of high sensitivity, strong specificity, precision less than 10%, high recovery, and lot-to-lot consistency. Based on the Sandwich-ELISA technique in combination with the enzyme-substrate chromogenic reaction as well as colorimetric measurement, the levels of TRACP-5b in the sample can be calculated.

    TRACP-5b (or called ACP5), highly and specifically expressed in osteoclasts, is an isoform of metalloenzyme TRAP. It is a dimer derived from TRACP-5a by proteolytic cleavage of a repressive loop domain and is the enzymatically more active form. TRACP-5b is a sensitive and specific marker of bone resorption and bone remodeling in patients with rheumatoid arthritis (RA), chronic kidney disease (CKD), and cancer with bone metastasis. And TRAP-5b was proposed as a serum marker for bone metastases in various types of primary cancers.

I’m searching for ELISA kits to detect TRAP in mouse plasma/serum and in culture supernatants of osteoclasts cultured on bovine bone slices.
I saw that Cusabio proposes a kit for the detection of TRAP with the reference CSB-E08492m.
Can you tell me if this kit is specific of TRAP5b produced by the osteoclasts (no detection of TRAP produced by other cells)?
Also, do you know if 100 μL of serum/plasma is necessary for the test or if a dilution of the samples is required?
Finally, as I would like to measure TRAP in culture supernatants, I was wondering if conditioned media (alpha-MEM containing inactivated FBS and penicillin/streptomycin) can be used as samples and if bovine TRAP coming from bone slices or FBS will be detected by the kit.
Thank you in advance for your consideration.

Thanks for your inquiry.
Pls check our answer:
TRACP is a good marker of bone resorption and osteoclast activity.
TRACP especially in the presence of tracp-5a (mainly from macrophages) and tracp-5b (mainly from osteoclasts) existed in the blood.
The determination of tracp-5b can reflect osteoclast activity.
CSB-E08492m is specifically for TRACP-5b, properly used for the mouse matrix samples.
The common samples are serum and plasma. The sample adding volume is 100ul. There is no need to dilute.
As for the TRAP in culture supernatants, pls arrange the preliminary experiment. Pls kindly note detects the mouse TRACP-5b not TRAP.
Any question, pls feel free to contact me.
