Background

The kit employs homogeneous time-resolved fluorescence (TR-FRET) technology for the detection of His-tagged proteins. It can be used to confirm whether the His-tag motif of a protein is recognizable by anti-His antibodies or to estimate the concentration of His-tagged proteins.

As illustrated, the His-tagged protein is labeled with an Acceptor (Ac-Protein His Tag), while the anti-His antibody is labeled with Europium (Eu-anti-His). Upon binding of the antibody to the His-tag on the protein, the proximity between the donor and acceptor enables fluorescence resonance energy transfer (FRET), resulting in a specific 665 nm emission signal from the acceptor. In the presence of other His-tagged proteins, they compete with Ac-Protein His Tag for binding to Eu-anti-His, thereby reducing FRET signal generation. Higher concentrations of competing His-tagged proteins lead to stronger competition and lower signals. The signal intensity is proportional to the binding between Ac-Protein His Tag and Eu-anti-His, with no washing steps required.

The BEST toddler shoe!!
Size: 18-24 Months Toddler, Color: Brooks Grey Leather
These shoes are 100% worth every penny. They are super easy to get on and off due to the fact that the tongue pulls back fully and they are flexible yet sturdy. They are excellent quality and have maintained great condition with my busy toddler at the park. The wide toe box provides great comfort for my little one’s wide feet. Buy the shoes!!!

Bummed they fell apart they are super cute
Size: 12-18 Months Toddler, Color: Raiden Camel Suede, Size: 12-18 Months Toddler, Color: Raiden Camel Suede
I’m so bummed because these shoes are so cute and highly rated but mine fell apart after only a few wears. They say light outdoor activities and I would assume they mean walking up and down the block in the neighborhood. My son is only 15 months old and doesn’t walk fast or far at all so it’s really disappointing they fell apart.

Perfect for beginners. Size is relative. Be sure to measure your baby’s feet. Kinda pricey but so cute. Well made and durable for my 11 month old Granddaughter. Love the denim look and the wide toe box and flexible sole.
