General description
Application
- as a standard to characterize the enzymatic properties of D5-CalB
- as an efficient biocatalyst to start the reaction to obtain (R)-ester via esterification of racemic secondary alcohol
- to investigate a “green” recycling route for polybutylene succinate (PBS) based on reactive extrusion
- to compare the esterification yield with adsorbed CaLB (aCaLB) and covalently immobilized CaLB (cCaLB)
Biochem/physiol Actions
Candida antarctica lipase B (CALB) possesses wide substrate specificity, high activity and high enantioselectivity, hence it is considered as a major enzyme in biotechnology. It also has the capability to perform in aqueous and non-aqueous reaction environments. CALB is used in transesterification, kinetic resolution and polymerization reactions.

How to Find a Lot/Batch Number for COA
Lot and Batch Numbers can be found on a product's label following the words 'Lot' or 'Batch'.
Aldrich Products
For a lot number such as TO09019TO, enter it as 09019TO (without the first two letters 'TO').
For a lot number with a filling-code such as 05427ES-021, enter it as 05427ES (without the filling-code '-021').
For a lot number with a filling-code such as STBB0728K9, enter it as STBB0728 without the filling-code 'K9'.
Not Finding What You Are Looking For?
In some cases, a COA may not be available online. If your search was unable to find the COA you can request one.
Which document(s) contains shelf-life or expiration date information for a given product?
If available for a given product, the recommended re-test date or the expiration date can be found on the Certificate of Analysis.
How do I get lot-specific information or a Certificate of Analysis?
The lot specific COA document can be found by entering the lot number above under the "Documents" section.
What solvent can Lipase B Candida antarctica, recombinant from Aspergillus oryzae, Product 62288, be dissolved in?
Lipase B is expected to be soluble in water. We are able to dissolve the enzyme in water for the enzymatic assay. We also have tested the solubility of Lipase B in 0.05M potassium phosphate buffer solution (pH=7.5) during quality control at a concentration of 10mg/mL. According to the chemicals encyclopedia published by the Royal Society of Chemistry, almost all organic solvents decrease lipase activity, with the exception of petroleum ether.
Is Product 62288, Lipase B Candida antarctica, recombinant from Aspergillus oryzae, lyophilized?
This lipase is a lyophilisate and may contain Gum arabic for adjustment of activity. The amount of Gum arabic in each vial is lot dependent.
How pure is Product 62288, Lipase B Candida antarctica, recombinant from Aspergillus oryzae?
Purity is not determined for this product. As is the case with many of our enzymes, the product is assayed for enzymatic activity, not for purity.
What is the molecular weight of Lipase B Candida antarctica, recombinant from Aspergillus oryzae, Product 62288?
Unfortunately, molecular weight information is unavailable at this time.
