Testbank, Question 133 Provide the reagents necessary to carry out the following conversion. CN 1. 2. 1. (CH3)2CHMgBr H30+ (CH3)3CMgBr H30+ CH3CH2CH2MgBr H30+ 2.
The lysis reagent is an acidic hypertonic aqueous solution comprising an alkali metal salt of an alkyl sulfate, a nonionic surfactant and a physiological salt. When combined with a second lysis reagent system, DC and RF measurements can be used to obtain at least 5 differentiating leukocytes.
• Do not expose the pipette tip to the reagent(s) already in the well. General Information • The final volume of the assay is 100 µl in all the wells. • All reagents, except the enzyme, must be equilibrated to room temperature before beginning the assay. • It is not necessary to use all the wells on the plate at one time.
