The BCAS4 (Breast Carcinoma Amplified Sequence 4) ELISA Kit is a Sandwich enzyme immunoassay. The microtiter plate provided in this kit has been pre-coated with an antibody specific to Human BCAS4. Standards or samples are added to the appropriate microtiter plate wells then with a biotin-conjugated antibody specific to Human BCAS4. Next, Avidin conjugated to Horseradish Peroxidase (HRP) is added to each microplate well and incubated. After TMB substrate solution is added, only those wells that contain Human BCAS4, biotin-conjugated antibody and enzyme-conjugated Avidin will exhibit a change in color. The enzyme-substrate reaction is terminated by the addition of sulphuric acid solution and the color change is measured spectrophotometrically at a wavelength of 450nm ± 10nm. The concentration of Human BCAS4 in the samples is then determined by comparing the OD of the samples to the standard curve.

SAVE YOUR MONEY - Protection Plan was money wasted
This 'Protection Plan' proved worthless for me. I purchased it for 3yrs. When I first ordered the HP 7301 All-in-one printer, I never got the first one to work. After HOURS of debugging and online support from HP it was determined that the printer was defective and needed to be replaced (FIRST printer never did setup or work AT ALL). Recently that printer failed again after about 13 months but well within the Asurion 3yr coverage. I then spend MANY HOURS over three days before being told once again by HP that the printer needed replacement and that they WOULD replace it. After many more hours escalating to a supervisor, since I had no means to package up and return the printer myself, that they would send a replacement in advance and allow me to send the defective back in the new printer's box. I had been without printing at this point for SEVEN DAYS. After I waited TWO MORE DAYS for them to 'check inventory' for the same model, I got a call from HP informing me that I was not going to get a new printer because: I HAD ALREADY HAD ONE REPLACEMENT and that was ALL I WAS ENTITLED TO. Of course this was the original printer to replace the brand new one that was DOA on its initial delivery. I lost all count of the massive number of hours I had invested to this point before HP RENEGGED on their commitment made to me more than twice. The current status is that I have a totally useless printer, had to buy a new printer, and have been stiffed for the cost of the HP printer AND the so-called Asurion 'Protection Plan'. In my opinion, Asurion put me through every possible hurdle to deny coverage under the plan, then after agreeing multiple times to send me a replacement (I have all the chat transcripts), they RENEGGED on coverage, which I believe was their intent from the outset. The notion that I had ALREADY received a replacement and was therefor ineligible for another is ABSURD on its face. The original replacement was needed to resolve a brand new DEAD ON ARRIVAL printer!!!

Buy a lot of tech and want guaranteed coverage, look no further.
The plan was very much worth it. My son's monitor went out for the 2nd time, the first I dint have insurance, and I filed a claim and got the whole amount back after it was determined it could not be fixed. All this process took no longer than one week. Grateful and will definitely but for future purchases.
