Every item is shipped based on the best shipping method assessed for the temperature requirements of that specific item. Items are grouped and shipped together whenever possible, and a separate shipping charge will be included for each shipping method required. Shipping charges listed below are from our US warehouses to the Contiguous US, Alaska, Hawaii, Canada and Puerto Rico. Shipping charges for countries outside the US and Canada will be determined once order has been received
Please note: We can not ship to PO boxesShips via FedEx Ground to Contiguous US, Alaska, Canada, Monday through Friday. This method is used for less temperature sensitive items such as lab ware and animal health products, bulky and/or heavy items
The Ret proto-oncogene is structurally related to the growing family of tyrosine kinase transmembrane receptors and is involved in GDNF signaling. By alternative splicing, two isoforms of the Ret proto-oncogene product are generated. The isoforms differ from each other by having either 9 or 51 carboxy terminal amino acids. The Ret gene products include two glycosylated proteins and, in tunicamycin treated cells, a non-glycosylated protein consistent with the predicted Ret molecular weight based on sequence analysis. Tumor-specific rearrangements of the Ret proto-oncogene have been identified in papillary thyroid carcinomas leading to the formation of different transforming fusion proteins sharing the tyrosine kinase domain of Ret. In contrast to the Ret proto-oncogene, the rearranged forms are constitutively phosphorylated on tyrosine and are translocated from the membrane to the cytoplasm.
