Investigators are studying a protein that must be phosphorylated to be activated. Which method could be used to separate the pho
Roman55 [17]

Answer:

There is two common methods to separate a phosphorylated protein from the proteins who does not have the phosphate group.

1. Western Blot test

The Western blot test is a method where we separate of the biological sample with SDS- PAGE (electrophoresis method) and then we transfer to a nitrocellulose membrane. We use a phospho-specific antibody to identify the protein of interest.

2. The ELISA test

this test is also a powerful method for measuring protein phosphorylation. Elisa test is more are quantitative than Western blot test and also shows great advantage in studies related with kinase activity. In this test we use a capture antibody specific for the desired protein, independent of the phosphorylation state. The target protein is binded to the antibody-coated plate.  and finally a detection antibody specific for the phosphorylation site analyzed is added. In these test it is possible to use colorimetric or fluorometric detection.

Write the formula equation for the reaction between hydroiodic acid and beryllium hydroxide
Aleksandr-060686 [28]
 The  formula  equation for  the reaction  between  hydroiodic  acid  and  beryllium  hydroxide      is as below

Be(OH)2  +  2 HI   =  BeI2 +   2H2O


Formula  of  hydroiodic is  =  HI
formula   of  beryllium hydroxide = Be(OH)2


1 mole  of  Be(OH)2  react  with   2  mole  of HI to form  1 mole  of BeI2  and   2   mole  of H2O

Which statements describe abiotic factors in an environment? Check all that apply.
olga nikolaevna [1]

Soil retains water and nutrients.

Several rocks rest in a stream.

Clouds create shade that changes temperatures

Abiotic factors are non-living components in the environment, or rather components in the environment that are not derived from life.

Explanation:

Abiotic factors interact with biotic factors to create ecoystems. An example of biotic factors interacting with abiotic factors include plants utilizing sunlight for photosynthesis and a wild beast drinking water form a watering hole in the middle of the savanna.
