CellStor Freezing Bags for Biotechnology Application

CellStor bags are used in storing biological products such as recombined therapeutic proteins, cells, monoclonal antibodies, vaccines, etc., for basic research/ pharmacology. It is also useful for storing plant-derived spores and pteridophytes in seed cryo-banks helping agronomic development.

ANIMAL BIOTECHNOLOGY

Recombinant Therapeutic Proteins
Process of forming the recombinant protein is called recombinant technology. Various processes were involved to produce large quantities of modified proteins, alter gene sequences and produce commercial products. Vectors were used as a vehicle to produce the recombinant proteins. These proteins can be stored in CellStor freezing bags.

Monoclonal Antibodies
A specific antibody is produced when tumour cells (Uncontrolled growth and replication) are fused with mammalian cells and forms hybridoma which continuously produces antibodies, and these are called monoclonal antibodies since its generated from a single type of cell. These cells can be stored in CellStor freezing bags at low temperature.

Genetic Material
Deoxyribonucleic acid (DNA) is the genetic material that carries information for the growth and function of all living organisms. It is made up of nucleotides with a backbone consists of sugars and phosphate groups. Based on the requirement, DNA is stored in short term (weeks at 4°C), medium-term (Months at –80°C) and long term (years at –80°C and –164°C ) storage. These DNA can be stored in CellStor freezing bags at low temperature.

Vaccines
Weakened or killed form of a microbe is administered to develop the immunity to a specific disease called Vaccine. The immune system considers as foreign material (antigen) and destroys them but the body’s immune system remembers them for the future encounter from the wild one (pathogen). Various ways of administration which includes intramuscular, sub-cutaneous, intradermal, oral and intra nasal.

Currently, novel cell-based cancer vaccine such as dendritic cell vaccine is in the limelight for therapeutic purpose. It is an immunotherapy which is a safe and induce antitumor immune responses and lengthen the survival of cancer patients. These vaccines can be stored in CellStor freezing bags at low temperature.

Cellular Components
Cellular components are biological materials which includes macromolecules such as polypeptides (proteins), nucleic acids, membranes and organelles. Most of the cell components are present inside the cell and some are present in extracellular matrix in an organism. These components are preserved at low temperature for research and drug discovery activities by storing in CellStor freezing bags.

Seed Cryo bank (Spores and Pteridophytes)
Cryopreservation of spores, tissues of gametophytes and sporophytes will effectively increase the genetic diversity with ex situ maintenance and longevity of the tissue. In vitro techniques found for germplasm collection and storage. CellBios provide customized freezing bags for the storage of seeds and tissues.
