Part Names
Parts of the software appear in the manual with the first letter of the word capitalized and the
entire word in italics. Thus, “job” refers to something the operator or system would do, but “

refer to a software component.
Terminology
This section presents descriptions and definitions of terms used in this document.
A
chemical
is a substance that can be purchased. A chemical probably has a CAS number
associated with it. The units of measurement suggest the phase or type of the chemical and the
information required, for example:
Units of M suggest an ionic solid (for example, ammonium sulfate)
Information required: formula weight, default stock, solubility, ionic makeup
Units of %w/v suggest a polymer (for example, PEG 3350)
Information required: default stock
Units of %v/v suggest a liquid (for example, Dioxane)
Information required: density
A
Sample
is a specific preparation of the protein that is set up in a crystallization experiment.
For example, a
Sample
could be 25mg/ml lysozyme in acetate, 50% BSA.
A
stock
is a liquid that is used in the lab:
NaCl is a chemical
5M NaCl is a stock
A
default stock
is generally the concentration of the aqueous solution of a chemical that is sold
by Hampton Research.
A
reservoir design
is a collection of chemicals that make up the reservoirs of a plate.
A
standard screen
is a crystallization screen that can be purchased from outside vendors.
A
drop design
is a collection of chemicals in the crystallization drop. A drop may consist of a
protein sample and a reservoir, or a protein sample and any collection of chemicals.
A
sitting drop
experiment is a vapor diffusion experiment with a reservoir design associated
with it.
A
hanging drop
experiment is a vapor diffusion experiment with a reservoir design associated
with it.
An
oil
experiment is a microbatch experiment with a sets of drop parameters and a volume of
oil associated with it.
A
recipe
is the set of instructions for preparing the chemicals specified by a design for
reservoirs and drops of a plate, including the quantities of stocks used in each.
A
class
is a classification for the chemicals used in the
CrystalTrak
database. Salt, polymer, and
buffer are classes.
A
property
is an associated descriptor which can be used to search or filter data. For example:
pH, autoscore=clear, acetate, and ammonium sulfate are properties.
