Product Details

Description

CUSABIO synthesized the recombinant gene by integrating the N-terminal 6xHis tag sequence into the targeted gene encoding the 111-291aa of the mouse Ms4a1. The synthesized gene was subsequently cloned into an expression vector. After cloning, the expression vector was introduced into the yeast for expression. The product was purified to obtain the recombinant mouse Ms4a1 protein carrying N-terminal 6xHis tag. The SDS-PAGE assayed the purity of this recombinant Ms4a1 protein greater than 90%. This Ms4a1 protein migrated along the gel to a band of about 21 kDa molecular weight.

B-lymphocyte antigen CD20 is a protein encoding by a gene named Ms4a1 in mouse and a gene named MS4A1 in human. CD20 is a specific marker on the surface of B lymphocytes. It is expressed on the surface of more than 95% of normal or malignant B lymphocytes. There is no expression of CD20 in hematopoietic stem cells, progenitor cells and other normal tissues. Studies have shown that CD20 has the function of calcium ion channels, which can affect the cell cycle, regulate cell proliferation and differentiation, and even lead to the occurrence of cell apoptosis by regulating the concentration of calcium ions in cells.

Purity Greater than 90% as determined by SDS-PAGE.

Form 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.
Buffer 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.
Reconstitution 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.

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
Notes Repeated freezing and thawing is not recommended. Store working aliquots at 4°C for up to one week.

 Q&A
Q:

I am asking about the purpose of the SUMO tag. Is it just for solubilzation? Can you please send the sequence with the tag?

A:
Thanks for your inquiry. CSB-YP015007MO1 is N-terminal 6xHis-tagged, not N-terminal 6xHis-SUMO-tagged. Kindly confirm.The complete sequence is as follows.

Target Background

Function
B-lymphocyte-specific membrane protein that plays a role in the regulation of cellular calcium influx necessary for the development, differentiation, and activation of B-lymphocytes. Functions as a store-operated calcium (SOC) channel component promoting calcium influx after activation by the B-cell receptor/BCR.
