Description

Porcine RNF4 (Ring Finger Protein 4) ELISA KitThe Porcine RNF4 (Ring Finger Protein 4) 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 Porcine RNF4. Standards or samples are added to the micro ELISA plate wells and combined with the specific antibody. Then a biotinylated detection antibody specific for Porcine RNF4 and Avidin Horseradish Peroxidase (HRP) conjugate are added successively to each

The Porcine RNF4 (Ring Finger Protein 4) 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 Porcine RNF4. Standards or samples are added to the micro ELISA plate wells and combined with the specific antibody. Then a biotinylated detection antibody specific for Porcine RNF4 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 Porcine RNF4, 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 Porcine RNF4. You can calculate the concentration of Porcine RNF4 in the samples by comparing the OD of the samples to the standard curve.

Great small hide & seek toy for small dogs.
Color: 4 Pack, Color: 4 Pack
If you have a very small dog or puppy this is great value for the money. My girl was tired after playing with it. The material and sticking are well made. Each little animal toy that you stuff inside the tree have squeakers and are well made. This is NOT for large dogs or power chewers but you got a small dog it is great. Most hide & seek toys like this are very expensive.

Great tug toy!
Color: Brown
The dogs are LOVING this toy! I have one crazy chewer but for some reason it’s really held up well so far! Some toys she can take apart in ten minutes. They’ve been tugging this non stop for days and it looks great! Perfect size for two dog tugs. Bargain for the r price.

Didn't last an hour
Color: Brown
Didn't last an hour. Mini Aussie playing with it by himself and had it torn it apart in less than an hour. Not worth the money.

So much sturdy fun for little dogs!
Size: Small 2"
Wow! My puppy loves these! He is entertained endlessly chasing after and nose scooting the little rubber balls! He really seems to enjoy the jingle sound and loves to chew on the balls also. Even with a lot of chewing from his little teeth, there are no marks. Sturdy, great toy!

Well made, perfect size!
Size: Small 2"
My dogs love these balls. They are the perfect size and hold up well for my 2 dogs, 7# and 9#. The bell is a nice change from the squeaky toys.
