Description

Guinea pig IgA (Immunoglobulin A) ELISA KitThe Guinea pig IgA (Immunoglobulin A) 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 IgA. 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 IgA and Avidin Horseradish Peroxidase (HRP) conjugate are added successively to each

The Guinea pig IgA (Immunoglobulin A) 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 IgA. 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 IgA 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 IgA, 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 IgA. You can calculate the concentration of Guinea pig IgA in the samples by comparing the OD of the samples to the standard curve.

Won't go through "hurricane" or chain-link fencing - dogs LOVE it.
Color: Orange, Size: Large
We've been using this size (large) for about 2 years now. Between our Doberman pinscher and the boxer-pitbull mix, they are tough on toys. These dogs have access to the Chuckit Ultra balls only under supervision and they run like crazy in the backyard while either fetching or holding onto the balls. It keeps our doberman out of trouble because she's running with a ball in her mouth and therefor cannot nip at the other dog when she gets overly excited. Tennis balls are lucky to last one play session with these guys, just for comparison purposes. When throwing the regular size, the ball occasionally went right through our backyard (chain link aka "hurricane") fence -- even though they shouldn't quite fit. The size large balls bounce off the fence; our only problem now is when one of the dogs does a soccer style head-butt and knocks the ball over the fence that way. After 2 years, one ball has a split down the side and two are discolored because they were left outside when we couldn't locate them after a play session. Overall I like these very much and appreciate how well they've held up.

My dog and I love this!
Color: Orange, Size: Large
The balls are larger and fit the Chuck It with the larger ball size perfectly. The balls are hard rubber material and have stood up to continued chewing after our dog picks them up. They bounce and are really hard wearing. Great product for the price!

Durable but don't give this to them as an everyday chew toy.
Color: Orange, Size: Large
My Catahoula loves these things. Great for a training aid and to let them get their zoomies out but not durable enough for an idle chew toy.

Fun, Durable Balls for smaller heavy chewers
Color: Four colors, Size: 5cm (ball only)
Perfect size and strength for my small dog that is a heavy chewer! She hasn’t been able to destroy and chew up this one like she has with every other toy! Definitely chew resistant.
