PROTRAN BA85 82MM 50/PKProtran nitrocellulose (NC) membranes are the most frequently specified transfer media in the world for a wide range of applications. Protran membranes are manufactured using 1% pure nitrocellulose to ensure the highest binding capacity possible.Other membranes referred to as "nitrocellulose" may actually contain large amounts of cellulose acetate, which will lower the protein binding capacity. Protran membranes have outstanding handling strength, and are compatible with a variety of detection methods, including isotopic, chemiluminescent (luminol-based), colorimetric, and fluorescent.Unlike PVDF membranes, Protran nitrocellulose does not require a methanol prewetting step. This makes Protran the membrane of choice for proteins, which prefer aqueous environments. Prior to transfer, the membrane is simply wetted in water, and then placed in the transfer buffer. No other pretreatment steps are necessary.

Disappointed
Color: S6-muti-color
These were great for about 20 minutes then they stopped squeaking...we have 2 left that I have saved but the other 4 do not squeak anymore...disappointed as my dog loves to squeak things...would not buy these again...My dog is only an 8lb dog too...but he can still play with the balls without the squeak...

Great Value for a ball my dog loves!
Color: S6-muti-color
I wish these ball were in the subscription program! My dog gets sooo excited by the new ball, but her interest in things lasts for a few days. She kills the squeak within 11minutes, but the squeaker stays in place rather than becoming a chocking or swallow hazard, and she still loves to chew it. Next, we must throw the ball approximately 723 times the first day, possibly 496 times on day 2, and just 3- 4 on day 3, at which point she will chase the ball before hollering "it's over here if you need it," while she checks on the chipmunk den. We currently have 17 of these balls in our yard (because we have given several leftovers to a less discriminating doodle next door). These balls hold up really well, get her extremely active for the first couple of days, and are a much cheaper than doggie daycare (after an active morning with a new ball, she is happy to chew on it and sleep much of the day). I always have these on hand!

Pieces chewed off
Color: white & green
My Aussiedoodle loves it. I throw it down the hallway, it bounces crazy, and he chases it. The only complaint is that he can't chew much of the ball part. So now I have to have it put away and brought out for special playtime.

Great toys
My 3-year-old Maltese destroys stuffed toys in short order. These toys with no stuffing keep her busy for hours without the risk of ingesting a bunch of loose stuffing. She loves them and carries them around the house making them squeak. Very durable for a toy destroyer like my little girl.

Fantastic toys! Your pup will love them!
My dogs love beating the ever loving **** out of these trusty squeaky toys. They’re durable, they last a long time, and they give my dogs plenty of entertainment. There’s no stuffing, which means zero cleanup. And the fact that you get 5 toys is a great value! They’re also super cute. I actually feel bad watching my dogs chew them.
