## BIOCHEMISTRY SPECIALIST

BIOCHEMISTRY SPECIALIST is awesome

## biochemistry Literature

Please read the instructions on the attachments.

1 page summary

Use pubs.acs.org or jbc.org or pubmed.gov

You can use a full paper or just a short paper/note

The name of the journal has to have biochemistry on it!!

## excel graph

Question.1: In this assignment you need to plot graphs on excel for below?

1. Linearity

2. Accuracy

3. Precision

4. Range

5. Specificity

· All data or numbers required for graph and calculations are in attached excel file.

· You can check online and for above 5. And if needed please add Colum and rows in excel.

· For more information about (how do I get results )see below in reference section .

Linearity Testing Results

Work to be done: For triplicate readings (see attached excel sheet) from each operator at each standard ‘% NaCl’ concentration, plot a graph of the calculated potentiometer reading (y-axis) versus the corresponding standard NaCl solution concentration used (x-axis) in MS Excel and calculate the following from the graph:

– Correlation coefficient

– Slope of Regression Line

– Y-intercept

– Standard Deviation (SD)

– Relative Standard Deviation (RSD)
