Question 8

What is 4-Arm PEG-NH2 (MW 10000) used for?

Accepted Answer

4-Arm PEG-NH2 (MW 10000) (4-Arm PEG-amine (MW 10000) ) is a multi-arm PEG derivative with amine groups at each end of four arms attached to a pentaerythritol core. The reactive primary amine or NH2 groups can react rapidly with activated carboxylic acids such as NHS esters to form stable amide bonds

Question 9

What is the sensitivity of this ELISA kit?

Accepted Answer

Assay sensitivity, including the minimum detectable dose, is listed on the datasheet. Kits that are assembled on order typically ship within 2-4 weeks.

Question 10

Do you ship this product with dry ice?

Accepted Answer

Some products, including certain cell lines and biologics, require dry ice for transportation, which carries an additional fee shown clearly in your quotation. Dry ice delivery isn’t always possible to every destination due to transit time or local restrictions, so we check feasibility in advance and you must store the goods at the correct temperature the moment they arrive.

Question 11

Is this product species cross-reactive?

Accepted Answer

Cross-reactivity data, based on available testing, is listed under the reactivity section of the datasheet. Contact us if you need reactivity confirmed for a species not listed.
