Is the pig IFN - γ ELISA kit in stock? How long will it take to arrive?

It is common for imported pig IFN - γ to have a delivery time of three weeks, and urgent needs cannot wait. Directly contact a domestic or imported spot agent and ask for specific information: whether there is spot stock in Hangzhou/Shanghai warehouse, batch number, expiration date, and whether it can be shipped via SF Express or flash delivery. Don't just ask 'Do you have the goods?' the other party may give vague answers. You can request to send a photo of the box body before placing an order to clearly see the expiration date and batch number, in order to avoid receiving a near expiration date. Within a budget of 1500-3000, domestic manufacturers with pig IFN - γ test kits should be able to find them in stock.

Even for urgent use, do not skip small-sample validation. Take 2–3 positive/negative porcine serum or known samples for spike recovery and matrix background testing, confirm that the recovery rate is within the acceptable range, and then run 60 samples. After receipt, record an unboxing video, check the lot number, expiration date, and whether the strips are damp, and report any issues the same day. Even for domestic stock, ask the sales representative to provide the quality control report for that lot number, focusing on intra-assay/inter-assay CV and the testing instructions for natural porcine serum samples.

60 samples, if single and multiple wells: 60 wells+standard curve 16 wells, about 76 wells, one piece of 96T is just right but the remaining amount is small; Double hole requires 120+16 holes and approximately 136 holes, with at least two pieces of 96T. If needed urgently, clarify the experimental design first, and do not buy only one piece. The result of the double hole is not enough. It is recommended to buy a detachable strip 96T. First, remove 2 strips for labeling and pre test 2-3 samples to confirm that the system is normal before mass production. This can also avoid transportation or storage problems that may cause the entire board to be scrapped. The domestically produced detachable strips within the budget are basically sufficient.

Local/Lower Yangtze River Delta warehouses in Hangzhou generally deliver in 1-2 days, and SF Express is basically next-day delivery; northern/Southern China warehouses may take 2-3 days. For urgent use, prioritize brands with distributor stock in East China, and do not have goods transferred from other regions. Agree with the seller on the arrival time and write it in the order notes, and request ice packs/insulated boxes during transport. It is currently a temperature-sensitive season. When receiving the goods, check whether the ice packs are still cold and whether the temperature record inside the box is within range. If it is overdue or the temperature is abnormal, refuse delivery directly.
