Description

Guinea pig LFA-2/CD2 (Lymphocyte Function Associated Antigen 2) ELISA KitThe Guinea pig LFA 2 CD2 (Lymphocyte Function Associated Antigen 2) ELISA immunoassay kit uses the Sandwich ELISA principle. The micro ELISA plate provided in this kit has been pre coated with an antibody specific to Guinea pig LFA 2 CD2. Standards or samples are added to the micro ELISA plate wells and combined with the specific antibody. Then a biotinylated detection antibody specific for Guinea pig LFA 2 CD2 and Avidin Horseradish Peroxidase (HRP)

The Guinea pig LFA-2/CD2 (Lymphocyte Function Associated Antigen 2) ELISA immunoassay kit uses the Sandwich-ELISA principle. The micro ELISA plate provided in this kit has been pre-coated with an antibody specific to Guinea pig LFA-2/CD2. Standards or samples are added to the micro ELISA plate wells and combined with the specific antibody. Then a biotinylated detection antibody specific for Guinea pig LFA-2/CD2 and Avidin-Horseradish Peroxidase (HRP) conjugate are added successively to each micro plate well and incubated. Free components are washed away. The substrate solution is added to each well. Only those wells that contain Guinea pig LFA-2/CD2, biotinylated detection antibody and Avidin-HRP conjugate will appear blue in color. The enzyme-substrate reaction is terminated by the addition of stop solution and the color turns yellow. The optical density (OD) is measured spectrophotometrically at a wavelength of 450 nm ± 2 nm. The OD value is proportional to the concentration of Guinea pig LFA-2/CD2. You can calculate the concentration of Guinea pig LFA-2/CD2 in the samples by comparing the OD of the samples to the standard curve.

Great ball for small dog (3.5 pounds)
Color: Burger Shape Assorted Color, Size: Small
I have been looking for a ball that my 3.5 pound Maltese puppy can enjoy. Up until now it was small balls were difficult for my little Rosie to grab. These balls at first seemed to be too big. But after a few minutes Rosie grabbed one of the balls in her mouth and has been crazy for these balls ever since. They collapse so she can get her mouth on it. They squeak each time she bites down. When I toss the ball, they bounce around like crazy and make a squeaking sound. They are so soft that it would be difficult to break anything. Also since they are not round, they do not roll under furniture most of the time. I uploaded a video of my little Rosie fetching one of these balls. Great toy!

Dog doesn't chase balls but does chase these!
Color: Regular Ball Multi-color, Size: Medium
This is a great product. My Aussie mix won't chase regular balls, but will chase these for long periods of time. Its the only way I can get him excercise right now. He holds them in his mouth constantly and has lost interest in his kong stuffed toys. This is my second time buying. The first time was great but the second batch had hardly any sqeak and not much air. Seller- please check your quality control! I have to go to another seller if these aren't consistent, because my dog needs the squeak in order to be interested.

Dog's BFF
Color: Burger Shape Assorted Color, Size: Small
My 10lb pup LOVES these toys. This is the second set I've bought. First set lasted 5 years. The squeaker can be a little irritating after awhile. But that's what he loves. Great toy for my little guy!

Best Balls Ever!!!
Size: Medium
These are the best balls ever! We have 2 very active ball loving dogs and these bounce very well and they actually hold up with active play and chewing. They still look brand new after daily use for months!
