The folins lowry reagent has maximum absorption at 650nm The alkaline copper reagent will show its maximum absorption at 650nm The peptide bonds absorb at 650nm The absorption maximum of blue colour is at 650nm Disqus Comments. The FC reagent contains phosphomolybdic/ phosphotungstic acid complexes The method relies on the transfer of electrons in alkaline medium from phenolic compounds to form a blue chromophore constituted by a phosphotungstic/phosphomolybdenum complex where the maximum absorption depends on the concentration of phenolic compounds. Back in 1922, Wu, who worked with Folin, applied the reagent to proteins, without CU2, so it was based on the tyrosine and tryptophane contents of the protein This procedure was used sporadically for some time and had a reputation for erratic results, probably because traces of contaminating CU2would increase the readings.

DISCUSSIONThe measurement of protein with copper and the Folin reagent has certain advantages(1) It is as sensitive as with Nessler's reagent, yet requires no digestion(2) It is 10 or times more sensitive than measurement of the ultraviolet absorption at X = 280 rnp and is much more specific and much less liable to disturbance by turbidities(3) It is several fold more sensitive than the ninhydrin reaction (23) and is somewhat simpler, as well as much easier to adapt for small scale. Folin reagent actually consists of two reagents in two, separate bottles, marked “A” and “B” Bottle “A” has a turquoise label, and bottle “B” has a green label IMPORTANT This test is to be used only after you have first tested your sample with Marquis, Mecke or Mandelin reagent It should never be used alone.

Estimation serum Creatinine By Folin’s Method (Jaffe’s Reaction) Creatinine is an anhydride of creatine It is formed in the muscle from creatine phosphate by an irreversible, nonenzymatic dehydration and loss of phosphate Serum creatinine (a blood measurement) is an important indicator of renal health because it is an easily measured byproduct of muscle metabolism that is excreted unchanged by the kidneys.
