SNIP measures contextual citation impact by weighting citations based on the total number of citations in a subject field.
SJR is a prestige metric based on the idea that not all citations are the same. SJR uses a similar algorithm as the Google page rank; it provides a quantitative and a qualitative measure of the journal’s impact.
The Impact Factor measures the average number of citations received in a particular year by papers published in the journal during the two preceding years.

To calculate the five year Impact Factor, citations are counted in 2014 to the previous five years and divided by the source items published in the previous five years.

The journal's title Analytical Biochemistry: Methods in the Biological Sciences declares its broad scope: methods for the basic biological sciences that include biochemistry, molecular genetics, cell biology, proteomics, immunology, bioinformatics and wherever the frontiers of research take the field.
The emphasis is on methods from the strictly analytical to the more preparative that would include novel approaches to protein purification as well as improvements in cell and organ culture. The actual techniques are equally inclusive ranging from aptamers to zymology.
The journal has been particularly active in:
- Analytical techniques for biological molecules
- Aptamer selection and utilization
- Cloning, sequencing and mutagenesis
- Electrochemical methods
- Enzyme characterization methods
- Immunological approaches
- Mass spectrometry of proteins and nucleic acids
- Nano level techniques
- Optical spectroscopy in all its forms
The journal is reluctant to include most drug and strictly clinical studies as there are more suitable publication platforms for these types of papers.
Apart from full-length original research papers, the journal also welcomes Review papers, and Notes and Tips - featuring methods that can be summarized in a shorter format article, including helpful "kitchen tricks".
