Molecular biology enzymes because of poor stability require cold or dry ice shipping and are therefore expensive to purchase and maintain. Recognizing these difficulties the scientists at G-Biosciences have developed procedures to stabilize a wide variety of molecular biology enzymes. These stabilized enzymes are offered as LongLife^™ enzymes.
The stabilized LongLife^™ molecular biology enzymes are highly stable, do not require dry ice or refrigeration during shipping and are easy to store and use. The LongLife^™ enzymes are stable for a year. The LongLife^™ enzymes are offered in convenient unit size that minimizes waste and suitable for education laboratories.  Currently we have several restriction enzymes and a ligation enzyme available in the LongLife^™ format.

LongLife^™ Ligation Enzymes
Ligation enzymes are routinely used in molecular biology for joining (ligating) of DNA strands during molecular cloning. T4 DNA Ligase is one of the regularly used ligation enzymes and ligates blunt and overhanging (sticky) DNA ends.
LongLife^™ T4 DNA Ligase Enzyme is a highly efficient ligation enzyme that does not require dry ice or refrigeration during shipping, is stable at ambient temperature and stable for a year.  Supplied as 75 units, which is sufficient for approximately 30 ligations.
