This Interleukin 4 ELISA kit uses the Sandwich-ELISA principle. The micro ELISA plate provided in this kit has been pre-coated with an antibody specific to Rat IL-4. Standards or samples are added to the micro ELISA plate wells and combined with the specific antibody. Then a biotinylated detection antibody specific for Rat IL-4 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 Rat IL-4, 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 Rat IL-4. You can calculate the concentration of Rat IL-4 in the samples by comparing the OD of the samples to the standard curve.

Nice bamboo cutting board set.
Color: Glue-Free Surface - Round, Set name: Set of 3 (S, M, XL)
So far have held up very well, and I feel better about not using plastic cutting boards. Good sizes, fairly easy to wash, but it’s a shame you can’t put them in the dishwasher. Overall a very good, sturdy product.

Best cutting boards
Color: Glue-Free Surface - Round, Set name: Set of 3 (S, M, XL)
Fantastic boards, easy to wash, dry and oil. Don’t put in dishwasher as the wood may split. Hand wash and dry it right away and stand it on its side to dry.

Wooden Cutting Board
Color: Glue-Free Surface - Rectangular, Set name: 12"L x 9"W
The purchase of a wooden cutting board was another selection in my quest to eliminate plastic from my environment when feasible. I had forgotten how great a wooden cutting board is to use. This one is solid, beautiful, and worked well with a sharp knife. It stayed firm on the counter, without sliding. The trough around the perimeter was effective in keeping any fluids from spilling onto the counter top. The size was perfect, allowing me to easily cut and contain the vegetables I was dealing with. Yet it was small enough to easily store and pull out for use. I followed the instructions for caring for the board, washing it with soapy water, drying it immediately, and wiping it with food safe oil. It’s been a solid purchase that will undoubtedly be a workhorse in my kitchen. The first use allowed me to toss my 3 cutting boards that I’ve been using for years and were worn. I’m anxious to see if it holds up with the daily use I’ll undoubtedly subject it to.

Best Comentary for the layman/bible teacher

The PNTC comentaries never dissapoint, they are the very best comentarys that i have found for those who do not read greek and may have a bit of bible college.. they are technical but not too technical, in depth but not too much. and you can always trust the General Editor DA Carson... i have several other comentary series but this is the best and all of them are rated very highly by the experts..
