Tag Info

Tag type will be determined during the manufacturing process.

The tag type will be determined during production process. If you have specified tag type, please tell us and we will develop the specified tag preferentially.

Form

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 before Lyophilization

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℃/-80℃. Our default final concentration of glycerol is 50%. Customers could use it as reference.

Troubleshooting and FAQs

Protein 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

Delivery time may differ from different purchasing way or location, please kindly consult your local distributors for specific delivery time.
Note: All of our proteins are default shipped with normal blue ice packs, if you request to ship with dry ice, please communicate with us in advance and extra fees will be charged.

Notes

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

Target Background

Function

Function in let-60 Ras signaling pathway; acts downstream of lin-45 raf kinase, but before the lin-1 gene product in controlling vulval cell differentiation. Plays a negative role in proximal germline proliferation in the mitotic zone. Required for progression of developing oocytes through the pachytene stage. In oocytes, inhibits the activity of the chloride channel clh-3, likely by activating gck-3. Plays a role in response to M.nematophilum-mediated bacterial infection by promoting tail swelling and preventing constipation. Involved in fluid homeostasis. In addition, involved in the up-regulation of lysozyme ilys-3 expression in the intestine in responses to M.nematophilum-mediated bacterial infection. By phosphorylating transcription factor skn-1 (isoform c) may play a role in increasing life span downstream of lin-45, let-60 and mek-2. By up-regulating cep-1 and down-regulating gld-1 expression in the late pachytene stage, plays a role in germline apoptosis in response to DNA damage. Regulates egl-1 expression in response to DNA damage, probably upstream of cep-1.; Suppresses germline tumor formation by preventing the dedifferentiation of secondary spermatocytes probably upstream of rskn-1.

MPK-1 thus may act not only in the control of individual processes but also in the coordination of contemporaneous processes and the integration of sequential processes in germline development PMID: 18073423
