Assay Principle
Intra-assay Precision (Precision within an assay): CV%<8%
Three samples of known concentration were tested twenty times on one plate to assess.
Inter-assay Precision (Precision between assays): CV%<10%
Three samples of known concentration were tested in twenty assays to assess.
To assess the linearity of the assay, samples were spiked with high concentrations of mouse TRACP-5b in various matrices and diluted with the Sample Diluent to produce samples with values within the dynamic range of the assay.

Materials provided
  • A micro ELISA plate ---The 96-well plate has been pre-coated with an anti-mouse TRACP-5b antibody. This dismountable microplate can be divided into 12 x 8 strip plates.
  • Two vials lyophilized standard ---Dilute a bottle of the standard at dilution series, read the OD values, and then draw a standard curve.
  • One vial Biotin-labeled TRACP-5b antibody (100 x concentrate) (120 μl/bottle) ---Act as the detection antibody.
  • One vial HRP-avidin (100 x concentrate) (120 μl/bottle) ---Bind to the detection antibody and react with the TMB substrate to make the solution chromogenic.
  • One vial Biotin-antibody Diluent (15 ml/bottle) ---Dilute the Biotin-antibody.
  • One vial HRP-avidin Diluent (15 ml/bottle) ---Dilute the HRP-avidin solution.
  • One vial Sample Diluent (50 ml/bottle)---Dilute the sample to an appropriate concentration.
  • One vial Wash Buffer (25 x concentrate) (20 ml/bottle) ---Wash away unbound or free substances.
  • One vial TMB Substrate (10 ml/bottle) ---Act as the chromogenic agent. TMB interacts with HRP, eliciting the solution turns blue.
  • One vial Stop Solution (10 ml/bottle) ---Stop the color reaction. The solution color immediately turns from blue to yellow.
  • Four Adhesive Strips (For 96 wells) --- Cover the microplate when incubation.
  • An instruction manual
Materials not provided
  • A microplate reader capable of measuring absorbance at 450 nm, with the correction wavelength set at 540 nm or 570 nm.
  • An incubator can provide stable incubation conditions up to 37°C±5°C.
  • Centrifuge
  • Vortex
  • Squirt bottle, manifold dispenser, or automated microplate washer
  • Absorbent paper for blotting the microtiter plate
  • 50-300ul multi-channel micropipette
  • Pipette tips
  • Single-channel micropipette with different ranges

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.

Target Background

(From Uniprot)
May play a role in the process of bone resorption. The osteoclastic trap acts on nucleotide tri- and diphosphates with higher affinity, compared with other substrates.
