■ 常见问题解答
Q:

We are interested in item CSB-YP004931MO. For the current lot, would you please tell me the buffer before the product was lyophilized? What do you recommend for reconstitution?
Would you have this information available to share?

A:
Thanks for your email.
The stock of this protein has just run out. The new lot is already under production and we will rush the preparation.
1. This protein has been delivered in liquid form in the following two buffers before: 1) PBS, pH 7.4, 50% glycerol; 2) 20 mM Tris-HCl, 0.5 M NaCl, pH 8.0, 50% glycerol.
2. If you would like Lyophilized Powder, we will add 6% trehalose to help dissolving later. The lead time will be extended for 3 working days. You can reconstitute the lyophilized protein directly with sterile deionized water. The general reconstitution method is as follows
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℃/-80℃. Our default final concentration of glycerol is 50%. You could use it as reference.
Any more questions, feel free to contact us. Nice day.

  • 功能：
    Part of the TCR-CD3 complex present on T-lymphocyte cell surface that plays an essential role in adaptive immune response. When antigen presenting cells (APCs) activate T-cell receptor (TCR), TCR-mediated signals are transmitted across the cell membrane by the CD3 chains CD3D, CD3E, CD3G and CD3Z. All CD3 chains contain immunoreceptor tyrosine-based activation motifs (ITAMs) in their cytoplasmic domain. Upon TCR engagement, these motifs become phosphorylated by Src family protein tyrosine kinases LCK and FYN, resulting in the activation of downstream signaling pathways. In addition of this role of signal transduction in T-cell activation, CD3E plays an essential role in correct T-cell development. Participates also in internalization and cell surface down-regulation of TCR-CD3 complexes via endocytosis sequences present in CD3E cytosolic region.
