Liquid or Lyophilized powder
Note: We will preferentially ship the format that we have in stock, however, if you have any special requirement for the format, please remark your requirement when placing the order, we will prepare according to your demand.
If the delivery form is liquid, the default storage buffer is Tris/PBS-based buffer, 5%-50% glycerol.
Note: If you have any special requirement for the glycerol content, please remark when you place the order.
If the delivery form is lyophilized powder, the buffer before lyophilization is Tris/PBS-based buffer, 6% Trehalose, pH 8.0.
We recommend that this vial be briefly centrifuged prior to opening to bring the contents to the bottom. Please reconstitute protein in deionized sterile water to a concentration of 0.1-1.0 mg/mL.We recommend to add 5-50% of glycerol (final concentration) and aliquot for long-term storage at -20°C/-80°C. Our default final concentration of glycerol is 50%. Customers could use it as reference.
Troubleshooting and FAQs
Storage Condition
Store at -20°C/-80°C upon receipt, aliquoting is necessary for mutiple use. Avoid repeated freeze-thaw cycles.
Shelf Life
The shelf life is related to many factors, storage state, buffer ingredients, storage temperature and the stability of the protein itself.
Generally, the shelf life of liquid form is 6 months at -20°C/-80°C. The shelf life of lyophilized form is 12 months at -20°C/-80°C.
Lead Time
3-7 business days
Repeated freezing and thawing is not recommended. Store working aliquots at 4°C for up to one week.

Incorporation of the gene encoding the Rat Cpa1 protein (111-419aa) into a plasmid vector forms recombinant plasmid, which is then transformed into e.coli cells. baculovirus cells containing the recombinant plasmid that can survive in the presence of a specific antibiotic are selected and cultured under conditions conducive to the expression of the gene of interest. The protein features a N-terminal 10xHis tag and C-terminal Myc tag fusion. Following expression, the recombinant Rat Cpa1 protein is isolated and purified from the cell lysate using affinity purification. Denaturing SDS-PAGE is then employed to resolve the resulting recombinant protein, demonstrating a purity greater than 85%.

Target Background

Carboxypeptidase that catalyzes the release of a C-terminal amino acid, but has little or no action with -Asp, -Glu, -Arg, -Lys or -Pro. Catalyzes the conversion of leukotriene C4 to leukotriene F4 via the hydrolysis of an amide bond.
Gene References into Functions
  1. gene transcripts for CPA1 in mesentery and other extrapancreatic tissues indicate that CPA1 might play a role in the renin-angiotensin system in addition to it'sfunction as digestive enzyme PMID: 22178042
  2. Data show that latexin protein expression was reduced after SNI, and the decrease of latexin was associated with an increase of the activity of carboxypeptidase A. PMID: 21572518
